You can get a dancers Number while spending money

I was out at my little hangout last night with my cousin. There was a dancer named Chrasima who I had tipped while she was onstage. She seemed to had disappeared when she got off stage but later she came along. The thing is she didn't sit with me she sat with my cousin(who handn't tipped). My cousin ended up getting a dance from her which later I found out was no contact. I had thought about asking her for a dance but after he told me that I chose not to ask. Even thought this girl gave a lousy dance she was still worth talking to because she ended up giving out the digits to my cousin. She spent most of the time talking to him while we were there. She didn't put much of a effort in working the room. I think she was the type that was tired of the guys who presented themselves as trying to get some ass and wearing the thug look. He was dressed in casual slacks and military style dress shoes(The shiney shoes).

I don't think she is looking for a boyfriend but just saw him as a nice guy. The sad part about it is that he isn't even looking to try and "hit it" even if the opportunity presented itself because he is still married. Though is separated from his wife who is up in VA while he is in GA.
I told him that if she wants to do it, let me take over from there if he is tryin to remain loyal since I am single. I think it depends on the type of club to as to whether dancers will give out numbers or not. My cousin always go's in and asks for numbers. A few of the dancers have given him there number but nothing ever became of it. Some of the dancers think he can be annoying at times despite being a nice guy. Maybe I should start asking for numbers more? or maybe I should just be glad I had a fun time which is what I came to do.
