Being a dancer, I have moments when I am selective, and it's moreso the customer and their demeanor and not how much money they are or arent spending. I generally try to avoid the guys that come off as assholes who think we are supposed to paw and beg for their $$$. On the other hand, if I notice a guy, no matter what he looks like, who has been just sitting by himself for a few mins, I will stop by his table and chop it up with him for a while just to make sure he is having a good time.
Once I noticed this guy who had been in the club for about an hour and no one stopped by to at least speak to him. He had a friggid look and came off as a shy, standoff-ish guy. He wasnt very attractive but he wasnt ugly either. He was just an average guy. I stopped by his table and sat down to talk to him and out of the blue he hands me a $100 just for taking the time to acknowledge him. I found out he was in the military, was leaving in three wks to go overseas, and his fam was pretty well off. After that night, he came in every night I worked, until he left, and spent a lot of $$ on me. He also brought in friends a few times before he left who still come into the club although he is overseas now. Similar things have happened with other guys who were just happy someone noticed them and made them have a good time.
I think some dancers forget the fact that one person can either start a buzz or keep people away from the club where you work. So as a way of maybe saying "hey you chose our club, have fun, and hopefully you will come back", I just try to make them feel comfy and welcomed. Just because they may not spend much that particular night doesnt mean they will not come back and spend. I have had many guys come back with friends because I was so nice that they figure most of the girls in our club were the same way and they would spend loads of $$. Afterall, you never know who enters a club and I'm a firm believer in not judging a book by its cover. (or maybe I'm just a happy go lucky person and I like to have happy people around me)
