1. “I work at the largest lingerie retailer in the country,” wrote Redditor @kittykatie0629 in 2017. “We had a security guard last night for the beginning of Black Friday. A Southern belle mother decided she didn’t want to wait in a 50-person line and was going to cut.” As you can imagine, that kind of behavior did not go over too well with the crowd, or the retailers. “Our security guard asked her multiple times to step to the back of the line or leave,” Katie wrote. “She proceeded to ream him with every curse word in the book. … This will be my last holiday in retail.”

2. Black Friday is scary enough for the employees who unlock the doors and let in the crowd of people who have already been waiting in line since the early morning hours. But what if you had to prepare for the big day at Walmart while the crowd gathered? “Because Walmart keeps the store open unlike, say, Target or other stores, we are setting up the merchandise right in front of the customers,” wrote Reddit user @LikeMike2224. “It’s literally like setting up a buffet in front of hungry bears or something.”

And once the products are set out, things can get messy. “When it came time to release the video games, a guy literally jumped over the crowd of people and into the game display, knocking it over,” he recalled. “Games went everywhere and it turned into a mob trying to get the games. No one was hurt except for the guy and a couple of COD games.”

3. It’s not just the violence and aggression that cause chaos on Black Friday; it’s the shameless behavior of shoppers who will do whatever it takes for the item they have their heart set on. “On Black Friday at ASDA (the U.K. version of Walmart) there were these microwaves that were like 70 percent off, but the store was so busy, you couldn’t move,” wrote Reddit user @VeryLazyLewis. “There were empty shelves all along the aisle up to where these microwaves were and a guy laid down, army crawled along the shelves, grabbed a microwave, and army crawled back with it.”

4. Black Friday is hard enough to manage when customers know what sales are being offered. But it’s even more difficult when shoppers don’t really understand the store’s deals. One Old Navy worker described such a situation—and the meltdown that ensued. “We would usually have several items on a table, but only one would be on sale,” wrote Reddit user @CeeDeee2. “It was clear though, there would be like T-shirts, skirts, and sweaters and the sign would say ‘T-shirts $5.'” Well, when one customer learned everything on the table wasn’t on sale, he “started flipping out about false advertising,” the employee recalled. “We wore lanyards and he grabbed my manager’s lanyard and started choking her.”
