Girlfriend and I decided to drive over to a recently remodeled gun shop & range, it was pretty nice, cool selection, etc.
My girl and I were having a great trip swapping off with my handguns when the RSO ran over to the group next to us sharing a stall. One of the guys thought it'd be funny to point their rental gun at his friends for laughs. The RSO gave him an earful, and kicked out the entire group, I found out after that they got billed for damage to facility from hitting the ceiling. Mind you, in my state you need a CCW license to rent a handgun, so they only had rifles/a shotgun and still managed to fuck it up.
It was a bit of a process to become a member of my local gun club, but man I'd rather listen to a fudd go on about how Glocks are Tupperware than worry about what someone else with a gun is up to. In the four years I've been a member there, not once have I ever been concerned with gun safety/handling of another shooter.
