There are only a few things I really hate in the world and few of those rank up there with valet parking. I know many people just love it. You don't have to worry about finding a parking spot in a crowded area, etc. That's a nice thing, I agree. But the part I hate is what you have to do to get that convenience.
Primarily, you have to give your keys to a complete stranger, who very easily could have a lengthy (violent?) criminal record. Not only that, but if anything happens to your car, they're not responsible (they tell you that on the ticket). So you pay a psychopath $20 to park your car, which may be scratched, wrecked, stolen, have its spare tire stolen (yeah...make sure you check that, especially if you have a nice rim on the spare...trust me...it happens) etc...and it's your fault. Or even worse, you could have the valet make a copy of your keys, then break into your house, set up hidden video cameras then hide under your bed for two days. Sound crazy? Well, That's exactly what happened to this poor woman.
Why on earth would you give a complete stranger your keys!??? OH YEAH! They're a "valet". Dumb....but everybody's doing it.
