Years ago, I was in a sandwich shop around a shady part of Indianapolis with a buddy. A kid in an oversized coat and do-rag comes in, and starts asking a lot of questions. "How much is that sandwich? Can I get it with this and not that?" All the while, kind of jerking around and looking very nervous. He finally jerks around one time too many and the snubby revolver he had stuck in his pants falls to the ground. He picks it up and runs out the door.
I've had several situations like that. Favorite was a guy who had a Jennings .22 stuck in the back of his pants. He tried to hold up a place I worked. He called the cashier (a big, middle-age single mother) something unprintable and demanded the money in the register. Her response was even more colorful, and she dared him to back up his threat. He then reached back and yanked on the gun
with his finger in the trigger-guard. I was in the next room, and all I heard was a pop and some girlish screeching. When Fulton Co. police showed up, the perp asked if they were going to call an ambulance, and one of the officers stopped laughing long enough to say, "yeah, in a minute, I guess."
On another occasion, I was in a really scummy supermarket called Ingle's, and the twitchy redneck in front of me in line reached into his pocket to retrieve his gun (a Rossi .38) and it slipped and fell to the floor. This is rural Georgia. Everyone packs. Much hilarity ensued. Bad guy was smart enough not to try and pick it up. (I remember the "security guard" being shocked that there were so many armed people in his store, and after several of us had our guns out for at least ten seconds, he woke up and started wildly shouting at US to "freeze! Drop your weapons!" Yeah, right.)
A third time was in a convenience store. The robber had come in and demanded all the money (in the middle of the afternoon). The clerk refused, at which point the robber pulled out his gun and slapped it on the counter, saying "that's why." The clerk simply grabbed it. The robber protested, and the clerk replied that the robber was welcome to call the police if he wanted.
I swear, despite the amount of criminal activity in Atlanta, it's a good thing the majority of them are dumb as stumps
