Back Payments

I have decided that you guys are right, I should be compensating strippers for all the time they have spent talking to me w/o asking for payment. Clearly it's really bad ethics not to have paid them. I think I should give them back payments the next time I see them. Do you guys agree? Also what formula should I use for calculating how much money I owe them? What hourly rate just for conversation? If I pay them for all of their time do you think that they will be appreciative of my better ethics?
