Money isn't everything.
I've been to places where the girls charge a lot more than here, yet the whole date was depressing, I could feel she was scared for her safety.
That's what happens when law enforcement is hostile to sex work, or when crime is rampant, or when society as a whole despises sex workers.
Here in MTL, I can give some ID and references, I can be screened, I'm a regular,
they know they are in no danger with me and will get paid the requested amount without arguments,
and I suspect that contributes significantly to the how pleasant the job is.
Also, as said before, hygiene, politeness, and all that. A coffee. A massage. Compliments. You don't have to pay extra or to be a stallion to make the date plasant for her.
