I've had a couple of good encounters recently, too.
A few days ago (getting a pumpkin shake at Culver's) the clerk said "I see you have a bullet there".
No, actually, I have 18. [Love my Glock!]
"Are you a cop?"
Nope, just a citizen. As long as the gun is visible it's perfectly legal.
We had a nice chat while waiting for my order. No screaming, no running away, no panic...
Take that, judge Adelman!
And yesterday getting groceries the bag guy asked "what's the gun for?"
Personal protection; what else would I use it for?
Again, no panic, nothing out of the ordinary.
