I have a policy myself that I will not give a lady less than 100 for 30mins and 200 for 1/hr even if her profile states she charges more but on the couple of occasions where I have given more the ladies haven't said a word, they just took the money and didn't even offer change. Is it they don't know what the rates are or is it they think I don't and are keeping quite so they can keep the extra. I wouldnt insult them by saying there's x amount of a tip because it's so small an amount it would hardly qualify as one?
