Why are the dancers here stuckup...

Why are the dancers here stuckup when it comes to other women? I use to enjoy going to the stripclubs but its not any fun anymore. I went in last week with a girlfriend of mine. After a few beers, I went up to tip one of the dancers and i stood there for a minute and a half at least and she STILL wouldnt come over to get it. So I sat back down. While on her tipwalk, she totally passed our table up. Ive never felt so ignored in all my life! We stayed to finish our drinks then left. Its a great looking club but i guess to get any attention you must be male.
