Hah! Marines are always welcome, anybody else needs an appointment. The only thing left in shop that is gun related is a wall full of trophies and plaques, medals ribbons etc from competition. So if they aren’t paying attention they might not even notice. I did have one Chatty Cathy but he went on and on about his Dad was in Vietnam in the Navy dropping sonar to find Rusky subs. Then I got the standard I was going to join but (insert reason here) speech. The guy would not let me go, one guy does vinyl siding so I got a whole bunch of info on that. Wore me out!
