We had a couple of guests sleeping in the spare bed on Friday night. I've just been in to change the covers ahead of more guests next week. When I took off the duvet I discovered a giant poo patch in the middle of one side ( human bum level.) Skiddy with lumps and some yellow stains around. One of the guests does have a digestive disorder so could be forgiven. Tiny chance it could have been the cat but doubtful as it was inside the covers. Anyway aibu to think that if you have a digestive disorder and this sort of thing happens you bloody well wear pants in someone else's bed. Also you strip the bed, you don't just leave a nasty surprise for the host. I'm just glad I decided to strip the bed between guests!
