Confused. I thought the purpose was to get money.

Ok. First time in Philly and visiting this club. The club looks nice from the outside and plenty of parking. Walked in after paying $20 door fee and was pleasantly surprise how nice it looked inside and choice of nice looking girls after scanning the room quickly. Was given a $12 free drink coupon at door, so went to bar and saw my type of girl at the bar, but she was busy. Saw two girls dancing on a smaller stage together. I walked closer to get a look and one of them came off stage and pulled me to the stage with the other girl. The other girl was immediately my type, so I knew I was ready to get some lap dances. Tip the one I like on stage and told her to come see me for some dances when she was finished on stage. When the two finished dancing on stage, they both went up some steps toward the rear of the club. I assumed the dressing room. So I sat there waiting and finally got tired and got up to see if the first girl at the bar was now available. She wasn't. Then I see the two girls come back out on the floor. I see the one I liked look directly at me, but didn't come my way. Then I saw her tag along friend grab a guy and go to the bar. The girl I liked was now near the bar where I was standing and looked dead at me and did not acknowledge me. She went and sat at the bar. What the fuck? Is my money not green? I have no clue what was going on. So I kind of got pissed and left the club. So nothing bad on the club, but that dancer missed out because I had about $400 ready to spend. Trying to decide if I might go back tonight to see if other girls or there, but I will definitely not ask for a dance from the girl again. Maybe I look like a cop. It's not the first time I have been told that. LOL.
