Ask for dance prices first

My wife and I like to travel and usually we visit one or two clubs in a trip. This time we came to Pittsburgh and stayed downtown. After dinner on Penn Av., Club Bush was an easy walk. Outside the place looks nice. It is located in a nice area in downtown. The cover was $15 a person, no drinks included. The club is very small and it was packed. A glassed wall at one side of the stage tries to give a sense of being larger without avail. The girls were all above average but I've seen way hotter and the variety was good but their we're not enough girls for the large crowd. Lap dances are in private cubicles and are suppose to be $30 a song and 3 songs for $79. We had a 3 song lap dance first and it was good. The girl and my girl had fun, butch sucked each other's tits and kissed. I got to suck both girls. She asked after every song if we wanted to continue and after 3 songs we wanted to check other girls, we payed $79 plus $11 tip. I left my phone in the room and the bouncer was nice enough to bring it back to me. The next girl was a skinny girl who was odd. We assumed it was the same prices and had two songs ut this time no sucking tits, no kissing and at the end she asked for $120 for 2 songs. We didn't want to argue so we just paid. Last one was a Ukrainian blond and before going in we asked for prices and she said $40 a song for a couple. We agreed and after one song of very minimal touching we stopped and she asked for $60, again I didn't argue and just paid and left very upset with how inconsistent they were with not only the dances but the prices. I'm pretty sure they ripped us because we were a couple.
