People who feel too comfortable on airplanes really must be stopped.
That's essentially the gist of the Instagram account, Passenger Shaming, which shares amateur photos and videos of "shameful" plane passenger etiquette to its one million followers.
One of their recent submissions was a video filmed a couple of rows behind of someone picking the dead skin off of their bare feet. The footage is not for the weak of heart.
This post was captioned: “Whatever the mind of man can conceive and believe, it can achieve," which they credited to Napoleon Hill.
The majority of comments were wildly unimpressed. Between the slew of throwing up emojis, a couple of Instagram users were able to articulate their horrified thoughts.
"After following this account for ages I just have one question. Who, exactly, are these people?" began one commenter.
"Nope. Can’t even watch it," posted another. "Freaking heathen."
"That's just wrong!" said a third.
The incident is reminiscent of several other bare-footed social faux pas that have gone viral in recent weeks.
In December, a funny clip of a passenger resting their foot on the armrest in the seat row in front of them, during a flight, infuriated and baffled the nearly 600,000 Instagram users who watched it. Then, on Jan. 1, Twitter user Erik Olvera posted a video of someone swiping through the Delta in-flight movie options with their bare foot, captioning the footage with: "I fly a lot and this, by far, is the most disgusting thing I’ve ever seen on a plane."
