On Reddit, the guest wrote that they “heard something crinkle when I settled in for the night” and posted a picture of the note they found under the sheets in their bed.

“If you’re reading this, then housekeeping did not change your sheets,” the warning written on a Courtyard Marriott notepad said. The image has since gone viral.
