When a valet "flat-beds" your car to you from service, does anyone ever tip them? Is it encouraged? A no-no? I have gotten to "know" my valet quite well after having him pick up and drop off my car more times than he and I can count over the past 3 months ... very nice guy. But then it got me to thinking ... does he think I'm cheap??? As I have never tipped him. If yes, what is the appropriate amount ... he drives 130 miles one way to get to me. Is that relevant?
