My "secret" of course is that while I might be dressed in shorts and a Tshirt, I am also usually wearing a pair of $800 crocodile moccasins along with a diamond studded Rolex. I guarantee you that I always get better service from hotel/wait staff than the guy dressed in the suit, especially a  suit that looks like it came from JC Penny's .Salesmen on a $75 a day per diem aren't exactly "big tippers" lol

 
I think it should go without saying that sex workers should be every bit as good at picking out "big spenders" as hotel and restaurant workers. You prove that I am right.
