Most of my working life has been in dealing with Joe Public, so I understand the Scrooges, and have seen more than enough of them. But what are you gonna do if they drop a lot of money down? After all, they don't tip, or tip very little, but they pay your lights or water or business tax for the year, whatever.
I'm not saying anything new here. It's not easy, but you have to balance out the fact that if you run enough of the tightfists away, you'll have to get rid of one of your girls to make up that difference.
Keep walking that wire.... 
You are right of course, I just felt like blowing steam. The staff is much better then I am at dealing with the public. I have a day job, so I don't mind telling a serious butthead to go someplace else. I must have a father complex since I am alot older then the girls that run the bar. I just want them to be able to pay their bills so they don't have to resort to other means to stay alive. Lot's of temptations out their for attractive but poor young females.
