Unwanted company

I was sitting at the bar in a strip club the other day. I ordered lunch while I was waiting for a girl that I knew. I was the only customer in the place. This this other girl that I had seen in there on previous visits was making her tip round after doing her stage dance. She asked if she could sit down next to me. I told her it was entirely up to her. We engaged in some small talk, she asked me about other clubs I had been in and she talked about the different places she had worked as a stripper. Two or three times, she asked me about going in the back for a lap dance. Each time, I told her I would let her know if I was intertested. She wan't a bad looking girl. I wasn't getting that connection. Meanwhile, my lunch arrived. I slid my stool down to where the bar maid set my plate and ate my lunch. It wasn't long before she slid her stool down next to mine, still trying to engage in small talk while I was trying to eat. After I ate my lunch, I excused myself to go wash my hands. On the way to the rest room, I saw the girl I was looking for, stopped to say hello to her. I returned to my stool and she was still there. She sat there until it was time for her to do her stage dance again...for almost 30 minutes.

Finally, the girl I was looking for came over. I told her I wasn't making a connection with this other stripper and I was glad when she finally left. There seems to be an agreement among strippers that when a girl is sitting with a "customer" the other girls don't interrupt.

Just wondering if anyone else has been in this situation. How do you send someone on their way without being rude?
