George Hamilton has two or three restaurants in every city he visits in which he keeps his credit card on file. He instructs the Maitre'd to add 25% gratuity to the bill and he never sees a check. Ever. Pretty slick, if you ask me.
Seems like a typically crass, Hollywood-style, ostentation, if you ask me (and you didn't.) I know several guys who do this. Seems like they're pretending to membership in an English style club in which, at the end of the year, the club members clear their accounts. Or rather, their valets do so for them. Why is it that snobs always emulate the English? Haven't they seen Monty Python's "Upper Class Twit" bit?
