A PASSENGER was not amused on a recent flight, so they scribbled a note on a serviette and handed it to a shocked flight attendant.

Shared onto Reddit by user Garwee20, the image had the caption: “My flight attendant mom got this napkin from an upset passenger” and has since gone viral, with more than 1 million views.

The complaint detailed offensive smells coming from a flatulent seatmate — something many of us can relate to, unfortunately.

It continues to ask the staff member to make an announcement over the PA system in a desperate bid to stop the farts.

But it may cross the line from funny to distasteful when it says the offending passenger should see a doctor “because they might have ass cancer”.

Users got in on the joke, with one saying: “Somebody crack a window!” and another posting: “I needed a good laugh, thank you”.
