I got a good lesson when I was 17. It was winter (in Fl) so I had my hoody on and it had one of those big pockets in the front and I had both hands in it. The shop keeps both went to draw down on me as I started taking my hands out of my pocket. I noticed what they were doing just as they saw my empty hands.
The next thing I heard was
"Son, do yourself a favor. Never walk into another pawnshop with your hands in your pockets. It will prolong your life."
And if I ever have to take a firearm anywhere, where I'm going to show it to someone. I have it in a case, action open, mag out (if applicable) and I let them open the case.
Some people just don't think about or know all the ins and outs. They get a bit nervous if they're new or unfamiliar with firearms. I'm just glad I don't have to deal with them
