The degree of idiocy displayed by some purported members of the species homo sapiens is mind-boggling. Case in point:
I shoot at an indoor range. The walls between the lanes are solid (as in opaque, not as in bullet proof). Between the side walls for each lane as a simply plywood bench top, set (at a guess) somewhere between 42" to 48" from the floor. Not high tech, but it works.
You know those plastic, stackable lawn chairs? The cheap, wobbly ones you can't lean back in because the legs collapse? The range has a few of those in the corridor outside the back-of-lane area, for people who want to wait outside where it's a little quieter while someone else shoots. I was in a lane near one end of the range one day. I was done, and all the brooms for sweeping up brass had magically migrated to the far end, so I wandered down that way to grab a broom. As I walked past the booths, I saw a child -- a boy who was maybe 8 years old, maximum -- standing on one of those wobbly plastic lawn chairs while shooting! An adult male (presumably the father) was behind the kid, but not steadying him or even near enough to grab him if he started to fall.
I'm a certified range officer, but I don't work at that range. Even so, that looked too dangerous to wait even the length of time it would have taken for me to get the safety officer. I just told the adult to get the kid off the chair because it wasn't safe. His excuse was that the kid wasn't tall enough to see over the bench.
I just told him to discuss that with the owner, and maybe they'd let him use one of the two lanes with lower bench surfaces, but it wasn't safe for anyone to shoot when they aren't standing on a solid, secure surface. Then I chased down the owner and ratted them out. I think the father (?) got a good talking to when they checked out.
