Economy class on an airplane seems to be getting more and more cramped and uncomfortable. As a result, passengers will go to more extreme measures to get comfortable while trapped in their seat for hours on end.
One of the prevalent things seen recently in the media is passengers taking off their shoes and socks and putting their feet in places they don't belong, including on the armrests of the passenger in front of them.
One man decides to take revenge on a man doing this to him and dumps water on his foot. Maybe he learned his lesson? Or will he have to ante up with some hot coffee next time?
