Indeed, I do keep fire extinguishers about our home (kitchen area and places with concentrated electrical circuits), and replace them over time. I also agree with the idea that you don't have to look like a commando just to be prepared. All I wanted to do is just not have to take off my shield that I was already wearing AIWB in the first place. To anyone looking at me, they'd see no difference. I just wouldn't have wanted it to be an unpleasant surprise and did the courtesy of just asking about it first.

Oh well. Perhaps I can just "forget" to take it off and see how bad it is for me. I'd rather have a dumb argument over this than for something life-threatening to happen, and I'm victimized by having inadequate tactics.
