I've seen officials joke to the effect of, "If I have to stay here and finish this, so do you." However, I normally put this kind of joke into the same category as the jokes about blaming your partner for overtime. I don't take them seriously, because no official I know would honestly put up with this kind of behavior as some means of "punishing" the coach.

If the coach wants to make a statement to his players by not watching the rest of the game, he can turn the game over to his assistant and walk away on his own volition. That'll say a lot more than getting booted for being an a$$.

As K-Bach later stated, the evaluator was not serious about it, and was most likely either joking with the guys he was sitting with, or he was testing them to see what they thought of this "approach."
