Just the other day some new shooter swept basically everyone in the building. She was shooting some .22 auto and it was her first time. Boyfriend didn't really take enough time to show her what to do and I think an indoor range is a horrible place for instruction - they should learn outside of the range first, then apply. But anyway, she fires like 1 or 2 downrange, then turns, bringing the gun, loaded, safety off, totally hot, finger on the trigger and looks for her boyfriend. I'm against the wall as my friend is shooting and the barrel is pointed directly at this head - through a thin hollow plastic barrier.
I get off the wall about to say something as she turns, passes the gun, finger still on trigger, over my chest, then past her boyfriend, the viewing window, and then down the entire line of people. Luckily right then, the bf noticed what she was doing and got her pointed down range. Fairly unsettling though, as he was a touch rough in moving her arm to guide it down range, and clearly something bad could have happened.
About a half hour later my friend said he noticed another guy down the line walk out of his booth, look around at this friends, pistol swinging with him, then step back to the line and fire a shot.
Some huge group of like 12 people had come in together and they were all completely new to this with no one on hand to show them what to do. That's when we decided it was time to leave, as I like having my brain in one solid piece without any holes in it.
