Talented but expensive

Had a night to kill while in town so decided to try out the Beach since I'd heard good things. Reasonable cover and there was a good mix of girls for varying tastes. After a few beers and sitting at the stage tipping the girls, two of the dancers came up to me and we started chatting a bit. Eventually they asked if I was interested in a dance in the back. They took me in back and started stripping, but seemed to be really into each other - which is not really a bad things, but after a bit, I wasn't really get a lap dance but a show. Before I knew it, they said that was it, but asked if I wanted to stay longer. I decided to end it there and they took me around front to pay. Like I said, not necessarily a bad show, just not what I was expecting for dropping $500. Stuck to sitting at the stage the rest of the night and tipping the dancers as they did their sets.
