Travelling via airplane isn't exactly the most comfortable mode of travel.
But, despite that, it's important to be conscious of the people around you.
There are a number of unwritten rules when it comes to flying etiquette, whether it's swapping seats with someone, not reclining your seat to within an inch of its life or standing up to let people out of the row - and you must not break them.
But, it appears one passenger didn't quite get the memo.
A video of a man's bare feet resting on the armrest in front was shared online, by Instagram user Gnarstypoepole to his Instagram stories, who then tagged the Passenger Shaming account.
You can see a pair of bare feet leaning on the armrest in front of him, before he goes on to hook his big toe onto the piece of metal on the back of the chair.
This left his toes spread out across the entirety of the back of the chair.
The disgusted passenger beside him captioned his post: "Update: he's rubbing them EVERYWHERE".
The man - seemingly unaware of his misconduct - continued to rub his other foot on the carpet of the plane to itch it, before tapping it against the bottom of the chair in front.
Hundreds of passengers walk up and down the aisles every day, so, not matter how often the plane is cleaned, wherever you wish to plant your bare feel will be dirty.
As well as it being rude, it's downright gross - so please, just don't.
