My worst flight ever was a night flight from Japan to Seattle (IIRC),
in which I was pretty much surrounded by the members of a boys sports
team of some sort (hockey, I think). I was tired, and ready for sleep -
but wouldn't get any that night. Those kids were hyper - and there were
three across in the row behind me. They all had newly purchased
electronic gizmos that they played incessantly. The one behind me kept
pounding on his with his fingers. Of course it was on the tray table
(which As I pointed out to him repeatedly, was directly connected to my
seat). He couldn't keep his hands off of it. The final straw came when
one of them went to the restroom. On his return he dragged his gizmo
across my face in the process of returning to his seat. I jumped up and
made quite a scene - and finally provoked a response from their coach.

Having had enough of that scene, I went and appropriated an empty seat
in a section reserved for the crew. They tried to get me to go back,
but I told them nothing doing - if they wanted to keep the peace on
that flight, they had better leave me alone. They did.
