I spent 18 years in Las Vegas where Valet is king.
I have many friends who are valet parkers. In Vegas it is a well-paying profession and most of them have held their job for many, many years. Unlike the hinterlands, these guys are professional and you take care of them and they take care of you.

As part of my job I visited many casinos daily and got to be known by hundreds of valet parkers. I tip decently and got great service. These guys make good money and wouldn't do anything to jepordize their job unless you really pissed them off and they thought they could get away with it.

They park the really nice cars up front for everyone to see; Ferraris, Lambo, Porsches, sometimes Vetts and always Crossfires.
