Personally, I feel as though this thread has drug on way too long. This is one of those not addressed in any book situations. So, if you feel it was nothing, say nothing. If you feel as though the coach is, by spitting on his hands (I find that offensive enough to
want to toss him
) and then rubbing the ball, helping out his players or altering the ball in some way, replace the ball, address it with the coach and move on.
Pretty simple, it would seem to me.
I can assure you of one thing, I will remember this coach and never shake his hand again at the plate conference.
