In the picture, an unnamed passenger is sitting in his seat reading a book next to a half-eaten tray of airline food and handfuls of trash that has been placed in the aisle.

The photo, which was titled “Man dumps his food into aisle after eating what he wants,” on Reddit and Instagram, has thousands fuming about the disrespectful actions, Fox News reported.

A Reddit user named, capitoloftexas, wrote, “Wtf is wrong with people?”.

Another, proscriptus, took a more direct approach, saying: “Everyone who walks by him needs to smack him upside the head.”

Others were just confused about why someone would behave this way.

An Instagram user commented, “Who does this?!?!”

“People are so unbelievable!! What kind of a person thinks that this is acceptable behaviour!! He should be fined for this,” another wrote.

While no one came to the man’s defence, a Reddit user who identified themselves as a flight attendant said: “Flight attendant here Can’t say for sure if this photo is the passenger’s fault but I’ve seen passengers do this and it’s infuriating.”

Since the photo was posted on social media, it has amassed over 34,000 upvotes on Reddit and nearly 5000 likes on Instagram.

More than 3000 comments have been made across both platforms.
