I worked as an RO at an indoor range/store for 4 years while I was in college. It was mostly for tourists who would rent our store guns and shoot a box or two of ammo.
The stories I could tell...
Like the drunk guys who stopped in during a bachelor party and wanted to "bust some caps".
The Hell's Angels members who would come to practice.
The wannabe gangsters who would shoot sideways and miss their target at 7 yards. Had a few tell me "Hey Man you better check this gun, the sights are off".
Had a lady walk in the store one day, look around all wild eyed and tell me she was going to call the police to report our store because guns were illegal and we would all be arrested. LOL
The ND's into the ceiling, floor and walls. Ah the memories...
I'm so glad I shoot now at an outdoor range and go on weekday mornings when it's empty and I have to place to myself!
