Sometimes it evens out on both sides. But MPAs definitely start listing off services like its a take out menu.
I've only done anal once with Marie @ TP but didn't have to tip her for it. She just wanted it cause she didn't have it for a while. Everything YMMV with these girls. Some don't mind including it to sucker you into seeing them all the time while others want to milk that appointment for everything its worth.
I just hate spas cause of the fucking tables. Not enough space to maneuver around to fuck. End up having to go all across the room on the couch, standing, back to table. Girl should be doing all the work, not me.
