Other people can do whatever they like, obviously, but there IS one situation in which I will give an SP a tip.
That is if at the end of the session she says, "So, are you going to give me a tip?"
I will hand her a few dollars from my pocket in exchange for that very valuable information that I should never, ever, ever book her again.
I'm a pretty nice guy, but the only time an SP asked me "so are you going to tip me" was aftr a very lackluster session,during which I realized she was way too buzzed. I wasn't happy, and upon being asked forthe tip, I said sure and gave her five bucks. I never even do this when faced with terrible service in a restaurant, but I'd just dropped 240 for a poor session , and a message had to be sent. She was also subsequently let go from the agency.
Topic has been done to death, but keep in mind the hourly wage of these girls is orders of magnitude more than the average waitress, I hardly think a tip is expected. The donation is the payment for the service. Ive never had a classy girl even mention a tip, let alone expect one. In fact, more often than not if I leave more than expected, they alert ms I've left too much. I tip cabbies, wait staff, bellhops, and the person who cuts my hair. I don't tip my lawyer, doctor, accountant o mechanic. These are professionals who charge a professonal fee. If I'm Extremely satisfied with service, then I show it.
I can't remember who it was, but a while back an SP membe here, well respected, said tips are always appreciated, but never expected.
