Been a while since I shared one of these stories.
Actually the reason it's been so long is because very little noteworthy things have happened. Some of that is because there are certain incidents that happen over and over again, to the point that I am numb to their occurrence (like people being in the store 10 minutes after we close).

So this is a special one.
It technically caused a nightmare.

It was a slow point in a day that had been super busy. My coworker and I were just standing up there enjoying our chance to breath. While my coworker was waiting on a customer I was straightening some stuff around the register when out of the corner of my eye I see a woman reach over behind our counter and grab a pair of scissors. Now first off, our register counters have a little wall that goes around the register and partially conceals that cup that holds our supplies (pen, highlighter, scissors)- so it's not like the scissors are just laying out there for anyone to grab. Oh no, she walked almost behind the counter to grab there scissors.

Well, it clearly states in our handbook that we cannot allow customers to handle scissors because this is a safety hazard. I start walking toward the woman and say "Excuse me, ma'am, but I can't let you use our scissors."
She responded aggressively, "You don't have to be rude about it! I just need to cut out these coupons!"
"I'm sorry ma'am, but it's a safety issue."
"Well you still don't have to be rude!" she snaps and tosses the scissors on the counter and storms off into the store.
The customer my coworker was waiting on is standing their slack jawed for a moment, before she said "What the hell is her problem?"
"Some people don't like being told the rules apply to them," I shrugged.
I mean really? I don't think any tone or phrasing would have changed her response. It baffles me how entitled some people feel! Those supplies are kept partially hidden behind that little wall for a reason, because they are only for employees to use.
Now if she had asked, I might have said yes and handed her a little pair of scissors. However, when people just walk behind the counter and grab stuff like that, I will enforce the rules down to the letter. People walk behind our counter all the time like it's no big deal. We have been robbed at this store before (not when I was there), and we are told from day one not to allow people behind the counter.

The nightmare I had last night was that I was all alone up at the front and a crowd of people kept jumping over the counter. I would tell them they weren't supposed to be back there and try to lead them back around, but more would come and invade that space. Finally got angry and grabbed a woman by the arm, causing it to just pop off. Then people started yelling at me, saying I was a terrible person, I should be fired for this. I think it is mainly from a fear that one day I'm going to tell the "wrong person" that they have to follow the rules too, and they'll bitch to my manager or corporate and I'll be sacked because I did my job. I've had to defend myself in the office before, but thankfully I had coworkers witness the interaction and tell my managers that the customer is lying.
