I was on a flight to somewhere or other, and I had an aisle seat. Across the aisle from me was a woman who talked on her mobile phone from the moment she got on the plane and was still talking as we went down the runway and only hung up after the plane had left the ground. The stewardess asked her to turn it off a couple of times and she completely ignored her.
What's worse is that because I was obeying the rules and had turned off my iPhone, I couldn't carry on listening to what I was listening to, which was the Paul Jones Blues hour that I'd downloaded from BBC Radio 2, and so I had to listen to her drone on and on. I wish it was possible to report that she was a top futures trader and I made a fortune by overhearing her conversation, or that she was a top heart surgeon discussing a critical case. She wasn't: she was discussion tedious administrative details at what sounded like a tedious public-sector body.
It's soon going to get to the point where they have mobile and no-mobile sections of the plane, just like they used to have smoking and no-smoking areas.
