Of course you may, it doesn't make it any more correct. Watching it for free and letting lots of people watch it in a canteen in a school are two different things. Sitting at home, all you need is a TV licence. It is a totally different situation with a gathering of people in a work place, even if entry isn't charged.
I know its stupid, I know its ridiculous. I was just trying to pass on some info. I can't be bothered to argue it, because I know I'm right. If you want, you can give the BBC a ring and tell them they're wrong too, they're the ones that told us this.
Cue "lol troll, lol leaving because you'er wrong, lol whatever" here. Glass stomach.
