I know I've had plenty of them but one my mom told me about at her part-time job takes the cake.
Last night she was cleaning stuff up in the backroom/holding area. She came across an item with the following sign on it...
Please hold until August 32nd.
She has an idea which co-worker it was and she thinks it's appalling that person is allowed to handle the store's money. LOL!
One of my co-workers who sat near me at my last job was a total Chatty-Cathy. She could literally spend an entire day calling friends/family/co-workers one right after the other. It drove me absolutely insane because she would tell someone something, call up the next person and tell them the exact same thing so I would have to hear the same story 40987539875 times a day.
What about you all? Annoying co-worker confessions go here.
