What's the most "Oh for f***'s sake" moment that's ever happened to you?

I'll go first. My dog was put to sleep a couple of months ago. One of the most traumatic things I've gone through personally, she was our service dog almost. Really helped with mine and my partner's anxiety. Heartbroken when she was put to sleep but that's how life goes. Anyway, about 2 weeks ago, we got a text from the PDSA saying "You missed your pets appointment at (Local practice). Missed appointments cost us £XX. Can you please get in touch and let us know why you missed the appointment." For fucks sake. Rang them and said "She's dead". Got an apology text less than an hour later. Edit: Need to clarify seeing as though there are a few arseholes in the comments. The vets who text me were the ones who put her to sleep. The vet who actually gave her the needle was the one who arranged the appointment. You gunna tell me they don't have any system in place to automatically cancel appointments for a dog they mark as dead? Or am I expected to go home and THEN ring them to inform them my dog is lying dead in their mortuary, still warm from when I was cuddling her on the floor less than half an hour ago? Actually, thinking back, I did ring them back about half an hour after I got home to confirm details for her cremation. So they knew full well that she was dead. If her actually getting put to sleep in the same building wasn't enough. I probably should have clarified tbh but there isn't half some nasty fuckers on this app sometimes. Had to sit there and read through someone completely satarising this for no reason. FOR FUCKS SAKE.
