I've been at my bar long enough to have the same kind of support. The owner and the staff all know that everyone respects each other AND the equipment! When someone commits a "party foul", such as you've described, or any others we all know...like swinging the mic by the cord, we make public fun of them so as to humiliate them enough NOT to commit said foul again.
Luckily, everyone has learned VERY quickly.
Did you spray the mic globe with Lysol?
