That my managers wouldn't let me have a weekend off for what would have essentially been my honeymoon because "It's small business Saturday and you need to be here."
I gave them over a month's notice and Small Business Saturday lasted all of an hour.
Thank God, I don't work there anymore.
I once returned a wallet to a police station like 15 years ago. They laughed cause there was money in it still. They then asked for my address so they could mail me a little something to commemorate the good deed.
Never got anything. 🙁 I just wanted to hang it on my fridge.
