I’ve been lucky and have never had an experience like this. I’m always completely up front about what I want and expect from a session.
I’ve been turned down a few times before the fact and I’ve had sessions where I’ve had to remind the provider what we’ve agreed to but I never go into any situation where there’s been any ambiguity about what I’m wanting out of the session.
I’d rather get told no before making an appointment then leave disappointed.
