There is only one place where I regularly tip $2: BJ's Liquor Lounge, where they just don't, for some reason, allow you to tip just a buck (you can, but you'll just get a "thanks," no dancing). I cop to it because there's no cover and I can enjoy my drink without any hassle from the ladies or bartenders.
Everywhere else is a dollar, unless I really like the stripper. I paid almos $20 to get in, I'm going to be as consistent as possible. And if you don't know the value of a single damned dollar, get out of my face and move aside for the girl who'd actually be grateful. Who in the hell rips money, especially in this economy?
This topic allows me to slam a girl in Story #1: At BJ's a long time ago, there was a girl named Mia or Mya (there's another girl going by that name, so I know this bitch who no longer works there by the tattoo of a pot leaf on the small of her back). I lay down the customary $2; she, without ever seeing me again, says I should tip $5 and shows me just her cleavage. Whatever, ho, and I left the stage.
Story #2: A long, long time ago at the local Deja Vu, there was a girl named Aspen who loudly complained (first onstage, then while trolling for dances) about not getting tips. For some reason she hones in on me, and after rejecting her she starts yelling loudly something to the effect of, "Why are you people so cheap?" I relented. I know I shouldn't have ... but actually Aspen gave a pretty good dance. And she rewarded me for capitulating later while onstage; I stuck a dollar bill in my mouth, and although it's not usually done there, Aspen took it with her mouth, then gave me a quick kiss.
Story #3: A long, long, LONG time ago, at this same Deja Vu, there was this dancer that was really long and slender with no tits -- a perfect template for a high-fashion model, but not stripper material. I watched her stage dance from afar. She tried to get into it (she wasn't bad, but it wasn't blockbuster), but for some reason (probably that she didn't "look like a stripper") no one tipped her -- and this was on a weekend night, where every seat along the rail was taken. Halfway through her second song, she started grabbing her things and leaving the stage before a chick on the rail threw her some money. Very sad.
