Holy crap.... I remember seeing something *almost* the same years ago at the old Dominion Range off Midlothian (aka the old, ancient, D&P range).
A couple of um, uh, let's just say "non-caucasians" came in... Baseball cap sideways, pants dangling showing their underwear, etc...
*you get the picture*
The two of them rented a 9mm, ammo, range time, etc... and decided to step away from the shooting lane, holding up the LOADED 9mm, up in the air, and were taking "selfies" of themselves. I lost my freakin' mind, packed up my 1911 .45 ACP and ran upstairs to complain. A person behind the counter, gazed out a plexiglass observation window and just said, "Yeah... we know. We're watching..."
Honest - even after all these years?? I haven't been back. That old place is just nasty...
