Hi jonrey, Welcome to massageplanet.net.
It's nice that your first post isn't a review. You are missing out on the 'shill' calling that usually goes on. If they do, most of them are just kidding so have a good laugh and keep posting.
Tipping is up to the individual. I asked an MPA if clients tip often and they told me NO. Regular clients that see them often are more likely to tip. MPAs do not expect tips, but appreciate tips because it's a sign that the client is happy with the service.
I look at it like this. I'll pay the regular rates when I receive regular service, but once in a while I run into an MPA that makes the session special. I'm talking about the attitude, kindness, how much they enjoy their work and sensuality. (I'm not talking about high mileage here, if you want high mileage there are cheaper ways than going to an MP.) When I have a session with an MPA like this, I usually do tip, just to say 'thank you'.
Jonrey, if you don't tip, you're not being cheap. Tip only if you want to.
