This could either be the stuff of holiday nightmares or a clever internet prank.
But whatever be the reason, this note a guest claimed to have found in their hotel room is probably one of the most horrifying things ever to be hidden amongst the bed sheets.
"If you're reading this, then housekeeping did not change your sheets!" says the note that's scribbled on a hotel's notepad paper.
A photo of the note was posted to Reddit with the caption: "Heard something crinkle when I settled in for the night."
The message has prompted other Reddit users to share their experiences as well, with one saying: "I walked into a hotel room once with an unmade bed, a half drank case of Busch under the sink, damp towels everywhere, and the TV on. It wasn't even the wrong room and it wasn't booked. Housekeeping just didn't even go in that day."
Now we're not sure about the location of the hotel or, for that matter, the name of the hotel (it isn't certain the name mentioned on the notepad paper is the hotel in question) but one thing's for sure - this is not the welcome note you want to find when you check a hotel room that you booked and paid for.
