for the regular dancers in the main theater, I'll tip $10-15 for a few minutes of them showing off/grinding right at my seat as they periodically mill about the audience during their half-hour-ish gigs.....
and I don't think there are "private booths" at Nob Hill??.....somebody correct me if I'm wrong!......there are the "arcade" and dark areas downstairs with lots of booths, but that is primarily for regular customers to use for free, right?......I don't think the performers typically do the "private booth" thing with customers at Nob Hill??.....
