Sometimes it's best not to think about what goes on in the places you stay on vacation. Some of the details of the average hotel room are horrifying: the bedbugs that travelers deposit as they pass through, reports of two-way mirrors, and the many more people who have access to your room than you think. Over the last few years, stories about hotel guests' peculiar kettle practices have been cropping up on social media and reported in various media. In the Life Pro Tips subreddit, a user warned people to avoid hotel kettles during their stay because they're used for almost everything but making tea or coffee, be it warming towels, cooking food, or washing underwear. Other users backed up the claims, with some saying that they had coworkers who regularly used hotel kettles for cleaning their undergarments or had even found a pair of boxers left in the kettle itself.
