Pull a loaded gun out in a gun shop in a threatening way and the heavily armed employees aren’t going to wait for the punk to shoot first
At a gun/pawn shop I frequent a few years back I was in there looking around and visiting with the staff and three out of place and acting strange came in and made a beeline for the gun section. They then started asking out of place questions and I watched the staff start slowly moving to different places, some of which I knew they had a firearm placed, most we’re carrying openly. I excused myself and started moving away from the gun section to an area I knew would offer protection and a place to fire, I was carrying a kel-tec P32 in my pocket.
The manager kept talking to them and two of them started looking about and realized they were covered from several angles, and they told the other guy hey we got to be somewhere let’s go and quickly made their way out the door. The staff stayed in place a minute or two and then went back to normal.
