I agree with you, once either party starts to question the other ones value or worth and the discussion revolves around money it is definitely time to move on.I think you missed something about a grandfather higher rate. I don't think it will "catch on" either but I didn't imply it was really a thing. Just something this one escort apparently tried to do with her client. I guess maybe my phrasing threw you off.
Having said all I have, I think the main take away is he should move on. The discussion of money has soured things for both parties.
Of course everybody has a budget whether that is $200 or $1000 but if you start questioning and having an argument over it then why are you seeing that SP in the first place.
This is exactly why I consider myself so lucky to have an ATF and a select few ladies that I know without question that I will enjoy my time with them.
