I wish I knew where this idiot lived and what restaurant he went to (IF he went at all. For all we know, he saw a guy on TV open carrying and imagined this whole thing), so I could open carry when he's there.
NOTE: I never open carry. I don't want to be the first on the bad guy aims at. I'd rather give him/her a "surprise". That said, I'd open carry just to see his reaction.
