What’s the oddest thing you’ve found in a hotel room in the UK?

Once had a disastrous weekend in Suffolk thinking we'd find accommodation on the fly and have a cool couple of days driving round wherever we fancied. Be all spontaneous, like. Well even 20 years ago that was a stupid idea, turns out. The first night we ended up in Felixstowe at a b&b. They turned down my partner when he knocked first. He did look a little shady with charity shop clothes and a scraggy moustache. I knocked later and miraculously they had a room. It was fine. The second night, we drove to a recommended b&b in a small village, and there was a sign on the door saying it was their annual linen count day and no rooms available. We ended up at a shabby pub called the Globe, which had a couple of rooms (not en suite). On entering the room we found a circling cloud of flies above the bed, a waste paper basket full of water, and a single sock in the middle of a rug.
