When I left my old workplace my colleagues organized a good-bye meal together. Standard office job, with regular guys. We had a great relationship and they knew I was vegetarian for 5+ years at that point and never had any issue with it.

So they asked which restaurant I would like to go and I was stupid enough to let them choose.

We ended up in a specialized Brazilian meat restaurant, where the servers go around with absurdly large pieces of grilled/fryed meats and would carve a piece to the guests. If you are a meat lover you can have easily 10-15 types of meats in a couple of hours.

Those assholes had a huge grin on their faces all evening, as I could only eat the sides from the buffet and had to refuse all meals from the servers about 12 time that evening. It was a truly memorable night, we even got drunk and laughed our asses off on our way home.

So yeah, not just kids can be assholes. We are still in contact till this day.
