While there have been plenty of stories about bad passenger behaviors, this, perhaps, takes the cake. In a video shared to the Instagram account passengershaming, a man was seen barefoot in his seat, picking off dead skin from his heel, and letting it flake onto the floor. Those who follow the feed were disgusted, with many calling for the man to face stiff penalties, including blacklisting by the airlines, imprisonment, and even "a plague to wipe out this half of humanity."
