Stripper acting different

I go to this club every so often. Not quite a regular but not quite a stranger. When I go in there is one dancer who I like, she is sexy nice body good to talk to. She has been at the club nine years. When I go in if she is there we talk and i usually get a private dance. Sometimes she comes back after we are done I usually don't expect it. The last time I was in ther the club was busy, I got a dance from her and she came back to the table, but this time she spent most o the night with me rubbed my shoulders down right flirtatious. She has not acted like this before, she never asked me for another dance. Part of me thinks she was waiting for me to ask for her number or maybe something else. She doesn't seem likt the OTC type but who knows?! Am I misreading this or what?
