yes, theres a whole bunch of unwritten rules, like identify if a customer is a regular for a particular dancer, and then don't try to take their attention away, bc dancers sometimes start fights over that stuff. As far as the club opposing it, it depends on the club. For instance to dance at Silverado, you can get turned away if the bartender working that day doesn't like you, they will make up excuses, then "go in the backroom to talk to the dance manager" and say you cant dance.
