Anecdotally, I was waiting in a swanky Houston restaurant... and the hostess seated one couple well before another couple who had 1/2 hour earlier reservations: it's all in the interpretation. If the second couple had been black, they might have seen it as racism... if the first couple had been draped in fur and jewels, it might have been seen as "classism". As it is, I just think the hostess was a bimbo (she screwed up our reservations and gave our table to someone else). Oh well.
