Attractive, active dancers but did not get any attention

It is worth a visit for the cover fee to see some very attractive dancers who put a lot into their dances. Good variety of sizes and dance routine. Came in expecting to buy a couple of their couch dances, but... Sat through the rotation, did a decent ( in line with others) rail tip but none made a personal effort to connect. Following their dance, two of the 5 came by to say thanks. The other three just went away . No " Would you like a dance?" Very unusual based on past visits. When I stayed, usually I had someone sit for a while and then ask to go back.

So, yes I will return to watch some dances some time in the future but don't understand dancers not making a effort.
