My worst customer was a woman in her seventies who was a regular at the supermarket I worked in back in the 1990s. She came in a lot, probably because she had reportedly been banned from both the other stores in the area, and we were the only other supermarket in town.
Sometimes her husband came in with her. He was the sweetest man you could meet so, naturally, his wife treated him like absolute s***, constantly yelling at and belittling him. After he passed away, she tried to get sympathy for having lost her husband. We didn’t feel bad. She was that awful to him.
She once deliberately squished her finger between two carts — I saw it myself — loudly yelled, “OW!”, and then yelled at the assistant store manager when he didn’t offer to compensate her for her pain and suffering.
She was an absolute nightmare at the checkout. She was extremely particular about how her groceries were handled, arranged, and bagged. God forbid you put a roll of paper towels down next to a head of lettuce or neglected to stack her packages of chicken “like records”; she would unleash a torrent of verbal abuse.
On one occasion, she was so verbally abusive to the cashier that the customer in line behind her spoke up.
Customer: “You can’t talk to her that way!”
Awful Regular: “Shut up and mind your own g**d*** business!”
Customer: “I will not mind my business! She’s a human being, and you have no right to talk to her that way!”
Awful Regular: “If you make me mess up this check, I’m gonna make you eat it!“
Our manager had to come over, and thankfully, our awful regular left shortly after. It should be noted that our cashier simply ignored her the whole time and kept ringing and bagging. It wasn’t her first rodeo with our awful regular.
The next day was her worst offense. She was being checked out by one of our newest cashiers, only sixteen years old. He placed her pears on the bagging area and was immediately greeted by a slap in the face. She was old and frail, and the slap was weak, but it was still shockingly unexpected!
Awful Regular: “You slammed my pears down! How dare you?!”
Of course, he had done no such thing. “Slammed” to our regular meant “didn’t cradle them gently with both hands before gently setting them on a soft surface”.
Cashier: “You crazy old bat!”
Awful Regular: “Manager! Where’s the manager?! You will be fired for insulting me!”
Our manager came over (sighing when he saw who was the reason for his being summoned) and listened to her complaint. This time, he was done with her.
Manager: “So, you physically assaulted a teenage kid, and now you’re trying to get him fired over it. You’ll be lucky if he decides not to file an assault charge against you.”
My manager looked at our young cashier with a look that screamed, “This is our way to be free!”
Cashier: “I won’t call the police and press charges if she is banned.”
Manager: “Well, there you have it, I’m afraid. Either you leave now and never come back, or we’ll need to call the police. My hands are tied. We’ll be nice and let you finish your current transaction, though! What will it be?”
She screamed and did not go down without a fight. She ended up with an assault charge AND getting banned!
