We had friends over for dinner recently. When we have people over we like to make it special and both put a lot of effort into the food we prepare, as I'm guessing do most people when they invite another couple over.
Our friends brought with them two bottles of wine, both half drunk, and one has been open too long and tasted vile so we (by agreement as a group) threw it away.
I felt it was a bit rude to bring half drunk bottles. They're good friends if a bit selfish at times but I felt a bit offended by it. I obviously didn't say anything but AIBU to think it's not really polite to bring ends of wine from your fridge to someone's house for dinner?
