Drew once. Didn't fire and didn't report. I and my family escaped unharmed, but the BG's next victims did not. I'm not happy about that.
On a lighter note, a couple of months ago I was at a gas station when a bum came up to me and started acting belligerent. I was unarmed and was just reaching for my wallet to use the pay-at-the-pump machine. I put my hand on my wallet but did not bring it out, and, with my hand in my back pocket, looked him in the eye and told him, "No, I won't give you any money." His whole demeanor changed instantly! He raised both hands, backed away, and became very polite. He said something like, "Well, sir, you have a good evening then" and left. Only afterward did I realize what my body language must have looked like!
