"Extra menu items offered in mid-session?"
I never had that conversation at EPM after many visits over the years.
This revelation seems quite odd....
Sounds like you were disappointed and irritated from the moment you walked in: Your concerns: "her weight, uneventful shower, 10 sec bbbj, rushed, you had to stop so she can reciprocate, nothing to write home about, she was pretty loose....". That is alot to unravel! Your description reads like a Motel 6 business.
Maybe your expectations were too high? Maybe your requests were unreasonable? Who knows? For 320. plus your additional 80.tip, you should have been a happy camper. Instead, you are furious. If you were so disappointed, why tip 80.? It sounds like you were "triggered" for whatever reason from the moment you walked in. Why didn't you leave if you were so underwhelmed. It would've spared you stress.
Personally, I know that "additional donation requests" are not tolerated at EPM. I also find it quite odd for an EPM provider to slam on the brakes and undertake "additional donation banter" in the heat of mid-session.
I have found that the hallmark of the EPM business model is that you never, ever, experience donation drama there unless a customer creates it.
It diminishes the business model and brand.
Maybe this girl just wasn't for you, maybe flawed, or maybe someone just had a bad day.
We have all been disappointed at times. Move on.
