I don't mean to speak out of turn here, but please have a thought for those of us who try to be considerate cell phone users.

EG, I always try to speak softly when using my cell in a confined space such as an airplane, restaurant, etc. I'd prefer not to have to use it at all, but sometimes it can't be helped.

That said, I do recall being in a bar on Whitehall, walking into the gents' and encountering a chap in mid shout. I've always wondered, did he begin the call: "Hi! I'm on the toilet!"
