When you check into a hotel, it's quite normal to presume that your room has been thoroughly cleaned - and your sheets changed.
However, one unfortunate hotel guest found a stomach-churning note on his bed recently that said: "If you're reading this, then house keeping did not change your sheets."
Not what you want to see on the first day of your trip.

The note was found by a guest staying at a Courtyard Marriott hotel and the image was shared on Reddit, reports Fox8.
The caption read: "Heard something crinkle whenI settled in for the night..."
A number of people responded and shared some of their hotel horror stories.
One wrote: Found a used condom under the side of the bed once when I stayed in an extended stay hotel in Florida. Disgusting. Housekeeping there was a joke."
Another said: "My husband found a pair of used underwear and a couple bottles of nips in the bed side table. They didn't believe us."
According to the Metro, one particularly horrifying story read: "A few years ago I and a co-worker stayed in a room for a month during some out-of-state training.
"A partial denture with four false teeth falls out of his sheets. He wasn't missing any teeth."
