Empty when I got there, empty when I left

Got there on a Friday night at 10:30, $25 cover. I go in and I'm the ONLY person there. The dancers were taking a smoke outside, not dressed for dancing. They call the dancers in. 15 minutes later 1 dancer is ready. I ask for a dance she says $20, okay. (given the $25 cover, this seems reasonable, other clubs are at $30, but with no cover.) The dancer is a "C", but I said "what the hell". So she's giving me a dance, not particularly erotic. The house hostess comes by, and talks with the dancer. The hostess say there's been a mistake, she should have charged me $40. This is in the middle of the dance. I got up and walked out. There's a reason nobody was there, they have no idea on how to run a club. I'm being polite !!!
