Varisty coach knows the rule #1

[Smitty]

Maybe "never" was an overstatement, but when a fan/coach is obviously agitated, as in the OP, there's nothing good that can come of engaging that person - especially during the game. The person that typically comes out looking like an a$$ is the official.

Of course if you know someone or someone asks you a casual question with respect, that's an entirely different scenario.
