I have no problem with that T. Just like middle school players need to learn how to play the game, some middle school coaches need to learn how to coach. (Most notably acceptable and non acceptable behavior)
I agree that most T's take care of themselves.
As for more warnings: (facetious, sorta)
"Coach, I am trying to count to 3 but everytime I get to 2 you keep interrupting me with YOUR count and I have to start over again!"
"Coach, if you are counting to yourself, please use your inside voice!"
As a rule of thumb, if I hear a coach start counting, I stop counting, but that is just me HA
