I used to work Valet for 8 months, loved the job.

A bit of advice: if you can avoid using valet, then don't use it! If you HAVE TO, tip a lil something when you park it (about $2) and tip good when the car is returned if they deserve it (about $3 or more). OR if there are VIP spots, ask the valet how much the hook up needs to be to park there because usually VIP spots are right up front and the car basically never gets beat on because there's no where it really needs to go except a couple of feet.
