If you spend some of your time massaging him do you get a discount? Maybe it should be a double discount because he is both not massaging you and receiving a massage for free at the same time.
I would bet that the vast majority of his clients have paid different rates to different providers. I also think it’s kinda weird he was monitoring your reviews of other providers and that’s how he found out you paid more to someone else.
For me no matter how hot a body is if I’m not attracted to the face I’m not interested. So I would rather miss out on someone who won’t show their face than get an unpleasant surprise.
