Not of sound mind
I'm surprised no one has mentioned the "sock-full-o-dimes" approach to this problem. Just keep sock full of dimes at your listening station. If someone makes an asshat request, you smack them with the sock. Next time they make a similar request, all you need to do is look at the sock and they should get the idea...unless they are the drummer. This is similar to the handgun approach.
by the way, what part of FL do you hail from?
