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.
I think he meant a regular provider not regular client. Another client of the provider showed him a private message from the OP who is a fellow client.
