Oh yeah -- I agree zebraman... AAU / Summer league ball -- do whatever you want and/or whatever makes for the most humorous stories afterwards.
For example, I *cough* know a referee that once addressed an AAU "coach" that was being quite the idiot by saying, "Coach, I'm ashamed for you."
The coach replied, "I'm ashamed for you!!!!!"
WHACK!
Important to note: There is nothing in the rule book about baiting a coach!!!
