I wanted to add that the more mature (age-wise) providers I reach out to 100% have a better manner in regard to responses, and much more patience as well.
The irony is that you can almost always tell what kind of a session you'll get from somebody simply by the way they talk to you via text. Rushed, no time, delayed responses, not answering questions? You're gonna get the same treatment in person most of the time.
If they appreciate you reaching out (provided you're respectful and polite), then you'll usually get that kind of treatment in return during a session.
I no longer go any further with anyone if I don't get a response within 2 hours. That's ample time to finish your session and respond.
