I was in Wally-World picking up some ammo. The counter was pretty crowded with several people getting fishing licences and such. There was a guy in front of me looking at a rifle and a scope. He had a stainless 1911 peeking out pretty good from under the bottom of his shirt. We finished our business at about the same time, so as we were walking away from the counter I tapped him on the shoulder, smiled, and quietly told him that he was printing pretty good. He smiled back and said "Yeah, that happens sometimes." He was nice, but I got the impression that he really didn't care if he was concealed or not. AZ IS an open-carry state BTW.
What's the "normal" protocol here? Am I supposed to let someone know if their gun is showing, (If they appear to be carrying concealed) or am I supposed to just be quiet? I'd WANT someone to tell me if I was no longer concealed.
What say the old-timers?
