Visited weekday early afternoon and again...

Visited weekday early afternoon and again later early evening. Usually about 4-5 dancers. Some decent and some fatties. I went there to get hustled for private dances at Oh Zone and during first visit only one girl approached me. During second visit only girl who approached me was one I had had private dances with twice before. I did not repeat but noticed she seemed to be the only one sitting with other customers hustling dances. Ended up wasting several hours. I do not know if one should approach dancers or wait to be approached.
