It can be nerve-wracking handing your car keys to a total stranger at   a valet station. You don't know if they're responsible drivers, what   their definition of "gentle" is, or often where your car is headed. If   all parking valets were trustworthy, there wouldn't be a need for the   "valet key" that prevents one from opening the trunk and glovebox.
  When we decided to delve into the secret life of valet parking   attendants, we expected some stories about concealed door dings, petty   theft or occasional hijinks behind the wheel. But we had no idea the   extent to which some valets routinely take liberties with their   customers' property.
  Our "confessor" (let's call him Mark) has worked both at upscale   hotels and small valet parking companies and has seen (and done) his   share of mischief. He shares his experience with us, no holds barred.   Learning how valets think and how some of them treat your property might   make you reconsider self-parking.
  Who's Parking Your Car?
  According to Mark, most parking valets fall into three general   categories. The first is student types seeking flexible hours and a job   that doesn't require much training. The second group is often working   nights after another job, and are often the most dedicated employees.   The third and smallest group are folks often unable to hold down any   other work, and they're the most prone to hitting poles in parking lots,   losing keys and disrespecting customers.
  "There's a big difference between valet parking companies in terms of   the quality of people they hire to park cars," Mark explains. "One   company I worked for tested applicants' reading and basic math, required   a copy of your seven-year driving record and demanded a background and   credit check. I guess they figure the ones with really bad credit  would  be more apt to steal from customers. Another company wanted a  high  school diploma — that's it. They didn't even read my application  before  offering me a shift."
  Our confessor pointed out that few driving skills are required, and   some companies employ people who don't have a driver license. "Valet   companies might ask if you drive a stick when they hire you, but if you   don't, you can just let other valets handle those cars. Some valets   aren't as friendly to stick-shift cars as they should be, especially   high-end cars like Porsches and BMWs. They might drop the clutch or   drive at 50 miles per hour in 2nd gear. Nothing that's going to destroy   the car, but it's unnecessary abuse. Most valets don't understand the   intricacies of driving performance cars either. They don't realize how   low to the ground they are and sometimes run over the concrete parking   stops, scraping up the car."
  It's All About the Tips
  Valet parking is a service job, much like being a server at a   restaurant. Pay is based largely on tips and most valets will usually do   their best to earn a good one. "Valets always find out about a good   tipper and make sure to take good care of that customer. My company   pools all the tips, so there's no competition for the 'best' customers.   But in smaller operations, if you're given a tip, you just pocket it."
  Many assume that the people with the nicest cars will leave the   biggest tips, but that's not always the case. "I drive all sorts of   luxury cars for people who tip very little or not at all. The customers   who have experience working crappy jobs are the ones who have more   empathy and tend to tip better. A lot of people who are 'forced' to   valet by the hotel assume they don't have to tip. Maybe they think the   hotel is paying the valets better than they are, but we're making   minimum wage plus tips."
  How much to tip? A survey of so-called "tipping guides" indicates a   wide range, anything from $1 to $10 depending on the situation. An   informal poll of Edmunds editors elicited a similarly wide array of   answers — anywhere from "nothing" to $10 or more at a hotel, but   averaged $2-$3, paid when retrieving the vehicle.
  Parking Pitfalls
  "There are the usual mistakes like dings or scrapes that are just   accidents," Mark explains. "Park enough cars and it's bound to happen,   especially on really busy days." The most common valet mishap is   misplacing keys, which has various origins. "If a lazy valet doesn't put   a ticket on the customer's keychain, or the key is incorrectly placed   on the valet board, or the ticket gets ripped off or the parking   location is written down incorrectly, or you, the customer, lose your   valet ticket, then we have no idea which car is yours."
  A valet's favorite scenario? "Let's say you've given us a valet key   to a car and it doesn't have a remote door unlock on the fob. But the   valet didn't mark down the right parking stall on the valet ticket. So   when you come to pick up your car, we don't know where it is. We don't   have a remote that can sound the horn either, so we have to run up and   down all the rows, trying the key in every car of that brand."
  The oddest mix-up? "The exact same rental cars got swapped between   two customers. No one noticed until one of them tried to return it to   Hertz. In that case, it took us two days to sort it out."
  What Annoys Valets Most
  It would seem like common sense to avoid angering someone with  the  keys to your car. If you really want to annoy a valet (at your own   risk), keep asking for your car to be brought around over and over again   to get something out of it. "If you tell us everything you want from   the car the first time, we'll bring it all back for you. It saves   everyone time that way."
  Another gripe is forgetting to explain a car's quirks, such as   complex security systems or aftermarket modifications — including   vertically opening gullwing doors. "When one of the valets pulled the   door open [on a 2005 Mustang convertible], we heard a horrible crunching   noise and the door wouldn't move. What the owner had neglected to tell   anyone was that he had a 'Lambo' door conversion kit on the car, and   that the door didn't open as normal."
  A favorite pet peeve of many valets is cars that reflect poor   personal hygiene — they may smell, have trash everywhere or look like   they've never seen the inside of a car wash. "When you're afraid of   contracting a disease by sitting in the seat, it's generally a bad   sign."
  The worst is forgetting to leave the keys with the valet on a busy   day, far easier to do these days with so many "keyless" ignitions. "We   can't move the car, and it clogs the driveway while we have to track you   down somewhere."
  Revenge of the Valet...or Just for Fun
  If you're particularly rude, aggravating or have stiffed on a tip in   the past, there are a number of things the valet staff might do in   response. Notably, most valets won't show annoyance or anger the   customer. "First and easiest, we'll take a long time to bring your car   up, and we're not going to take the time to put your seat and mirrors   back the way they were. But I have known valets who lower tire   pressures, change climate and radio settings, or intentionally ding the   door or scrape paint in a place where it's not easily noticed. There's   nothing better than getting your revenge and getting them to tip you, too."
  When you're not around to see it, there's a lot valets do:
    - Blast the stereo and change the radio stations: "Any time that I   have a car with a good stereo in it, I take an extra minute to check out   the sound quality. I also change the satellite radio station, but I   almost always change it back."
   - Speed in a parking structure or on the street while driving to a   lot: "We once had a running contest going to see who could get the   fastest top speed inside the hotel parking structure. I set the record   with a 55-mph run in a Porsche 996 GT2."
   - Rev the engines of performance cars: "I can't help revving up the  engines of the cool cars I get to park. My favorite was a Lamborghini  Gallardo.  I drove it straight to the top floor and called all of my  friends in my  phonebook. I said, 'Guess what I'm driving!' then stuck  the phone out  the window and revved the engine. Heck, I even called my  parents and did  that." 
   - Drift: "After our parking garage is cleaned, we have to re-park  all  of the cars back in the structure. Of course, having an empty, wet   parking structure just begs for a little hoonage. I take every  rear-wheel-drive rental car and find out how well they drift going up  the structure. Surprisingly, the Chrysler Crossfire does a great job.  Gotta love rental cars; they take the most abuse." 
   - Go through the customer's property: "Though I personally never   rifled through anyone's belongings, I hear plenty of, 'You should have   seen what I found in this person's car' while we're standing around   waiting for cars to pull in."
   
  With all these shenanigans happening with your car, is the management   aware? "Our manager doesn't know about most of this stuff," Mark   admits, "but he helps cover up our mistakes sometimes. He always keeps a   container of rubbing compound and wax in the office in case there's a   scrape. We'll clean and buff the affected areas and pray the customers   don't notice. Most of the time, they don't. I have seen managers rub  out  many small scrapes and never report the incident."
  Advice for Customers
  Remember, you are giving one of the most expensive things you own  to  a complete stranger. You would be surprised how far a smile, a good   attitude and even a little pleasant small talk will get you. If you're   pleasant and tip, most valets will go way beyond the call of duty.   Here's what to keep in mind, according to Mark:
    - Realize that it's not all about you: "We're dealing with many,   sometimes hundreds, of customers a day. Time is money for us, too." 
   - Don't leave valuables or anything illegal in your car: "Not if you   want them to be there when you get back. We've found drugs, adult-only   items, even guns." Smaller items are more likely to be taken. 
   - Clean the interior as well as the exterior once in awhile: "And for God's sake, use a trash bag." 
   - If your car is damaged or anything is missing, tell the valet   manager and get a copy of the incident report and the contact   information of their insurance company. Don't accept it if he asserts   that the "release of liability" language on your ticket absolves them —   it won't stand up in court. 
   - Valets at a hotel usually work for a contracted company, so if you   have any problems with their service, notify hotel management. They can   help resolve disputes in your favor. 
   - Be wary in major cities where valets must park cars on the street.   If a valet parks illegally or forgets to feed the meter, the customer   can get stuck with the ticket. 
   - Tip a little when you drop off the car, especially at a hotel, and   your car will get better treatment: "The valets will be more likely to   'keep it close' in the hope that you're a good tipper and that you'll   reward them for bringing up your car quickly." 
   - Evening shifts are the roughest for hotel valets: "We work our   butts off to park all the cars of the people checking in and barely make   any tips. The morning shift makes big tips the next day when people  get  their cars to go places or check out of the hotel." 
   - Reward a valet for working hard. "If it's raining and he appears   with an umbrella, or he towels down your seat to keep you dry, he   deserves a bigger tip. But don't worry about not giving a tip if you   don't like the service." 
   - You get what you give: "Your car will usually get the same treatment that you give us, for better or for worse." 
   
  There are plenty of honest, hard-working parking valets out there who   want nothing more than to serve their customers and earn a living. So   when you drop your car off, it's a good idea to look your valet in the   eye and acknowledge that he's a person, too. If not for that reason,   then at least to improve the odds of getting your car back exactly as   you left it.
