First time in MN strip club....

First time in MN strip club. Small crowded place with metal stools and tables. Nice looking girls of mixed races. Before I got settled in, waitress stopped by, I told in a little bit. But she said you must get a drink. First bad impression. Ordered my drink and she came back with it. No smiles. Apparently she's the only waitress working there. Anyway, I tried to ignore and enjoy my time. Nice dances on stage. Couple of girls stopped by, they seemed to be very nice to talk to. However, in a few moment the rude waitress came back, asking what is my next drink, even my current one is not done. I refused, she said I need to leave if I don't have a drink. I said ok, and left. Pissed off by the waitress. May not go back unless I here they got some friendly people.
