Take this video, extrapolate it for every journey in a public plane, and then take into account idiots like the guy in this video who seemed to have a hidden camera. Its a wonder they any of them don't lose it. If any of them were honest about it, their reactions would see them cast irrevocably as arrogant, ill-mannered big-headed non-performers (this tag has to be included, it lends weight to the rest of the adjectives) louts.
Is it any wonder that they prefer playing overseas, in places without plane journeys?

The comments are heartening though. Thankfully most people seem to find these videos offensive.
