The unnamed airline passenger was recorded using a foot file to grate her foot while sitting in the seat next to the window, Fox News reported.

The video, which was shared to the Instagram page “Passenger Shaming” earlier this week, and has since been viewed over 150,000 times, received immediate reactions from people disgusted by the passenger’s shameless grooming.

“How is (she) even allowed to do that! Disgusting and I would have raised hell if I were sitting next (to) her. YUCK!!” one person commented.

“Are you f***ing kidding me???? I am seriously losing all hope in humanity,” another wrote.

“Call the flight attendant and have her tell the pilots to have the cops meet them at the gate because a passenger was intentionally disposing of biohazard material on the plane,” another outraged commenter said.

“What in the actual hell is wrong with this woman? So wrong on so many levels,” one wrote.

This incident is not the first time travellers have posted their outrage for fellow plane passenger’s activities.

Last week, Passenger Shaming posted a photo sent to them of a woman using the plane’s aisle to allow her child to go to the bathroom. The commenters were equally as stunned and critical.

Also last week, a man was shamed on a New Jersey train for sanding his foot with a power tool.
