Like the guy that wants to talk to you while your playing, I have a rule. No eye contact and ignore him.

This is a pet hate of mine, particularly as I can't hear them, so I tend to mouth "I can't *effing* hear you". Things took a turn for the worse at a recent gig, when the punter responded by typing his request onto his phone. I then said "I can't read that - I'm 47". The next time someone does this to me I'm going to lick their face.
I'll let you know how this pans out.
