The restroom nightmare....... royal pain in the ass.. I've also seen a Masaad Ayoob training video on proper public restroom tactical etiquette. It's out there....he has an answer for everything..... except, what to do when trouble occurs during mid wipe.
some people don't like their guns to print- so they squat down instead of bending to get stuff off shelves.
you'd be surprised how oblivious the average joe is, and odds are they are looking down the aisle, shopping for an item, fondling their iphone.... doing anything but looking at your 4 oclock so i dont let it bother me too much, but when i first started carrying I squatted every time
