As an instructorA pitching coach turning away a client.....stupid. The answer should have been "sure I'll teach whoever will pay me."
DD's pitching instructor schedules the first lesson for free. This 'lesson' has two goals. First of all, the instructor wants to review the student's current status; mechanics, athleticism, etc. It's also an opportunity for the student (and parents) to meet him and ask questions concerning his program. After this lesson, he reviews his program and asks the student/parents to think about it, contacting him at a later time if they intend to continue.If the girl wants to learn to pitch and the parents are in a supporting role, then by all means, full steam ahead.
What used to pain me was seeing girls desperate to please their parents when it was clear that they did not have and never would have the athletic ability they needed.
So, it a pitching instructor can help in the latter case, if possible, wouldn't that be a good thing?
