We had a friend who did this to us, a group of friends stayed and her partner kept making digs at us, how we were loaded, had a cleaner, wasted money in his view (because I served up a fresh meal the second night and didn't just give the leftovers from the previous night, and we are not in any way loaded, but he had a major chip on his shoulder)
Anyway when they left their bedroom was basically trashed, quilt screwed up and half off the bed, pillows on floor, what I can only assume were sex tissues under the duvet, towels strewn across floor, furniture misplaced, rubbish laying around.
It was very odd, we all, inc the other friends who stayed, assumed it was a passive aggressive the cleaner can deal with it and fuck you thing from him. I've not had them back since.
I just can't imagine doing that in someone's house. The thing is she even checked the room to make sure she hadn't forgotten anything before they left, and simply left it like that. And she's not slovenly in her own home, so it was clearly deliberate.😱
