I would like to nominate the man on my flight back from Barcelona to Heathrow last night. I didn't know he existed until landing.
He stood up as soon as the plane stopped taxiing, was chewing gum, and had one of those truckers caps that seem to sit on top of your head rather than actually fit.
Also, the man in the row in front of him who was completely bald on top but had kept the side and back long and had put it in a top-knot style, just around the back of his head.
Clearly I was very judgy last night.
