My personal 2 cents. for any service provider that is in business for HIMSELF, and will pocket 100% of the fee, I would not consider a tip. I feel that if an escort is charging $300+ for an hour, that's more than enough for the service he will provide me. and as he doesnt have to divey it up between staffers, he is being sufficiently paid for his time and service. I wont bargain the original fee and feel he is charging what HE considers adequate for his time and service. I believe that those that give a tip are doing so to make themselves feel good and insure a return visit with said Service provider.
