Flight attendants know a lot about travel and often give advice. One attendant recently talked about a gross topic: plane bathrooms and what people do in them.

Gemma Sophie shared a travel tip on TikTok. She said some things on planes really disgust her, and clean people might want to know.

This is not the first time a flight attendant shared travel advice. Another attendant said they greet passengers for a reason, not just to be polite.

Gemma shared her top annoyances as a flight attendant, including people being sick in the sink and changing diapers in the cabin.

She also said people using plane bathrooms without shoes is disgusting.

The video was viewed thousands of times and got people talking. One person said it was their nightmare.

Another person said no shoes in toilets is bad. The floor is always wet.

Many people said they can't believe people go shoeless in plane bathrooms. Gemma said it happens too often.

Flight attendants and health experts advise against using plane toilets without shoes. The liquid on the floor can be bodily fluids.

This can cause hygiene and infection risks. The floor has bacteria, viruses, and fungi.

The liquid on the floor is not just water. There are other things to consider.

For example, in an emergency, you need shoes to navigate debris safely. This is another reason to keep shoes on.

If you want to take your shoes off, consider bringing slippers or disposable shoe covers. You can use them to walk around and use the bathroom.

It's worth noting. Nobody wants their feet covered in germs.
