Answer 1

so why do it

Answer 2

"It is a good idea to give your name and address and to be polite, if you are rude and swear they may be able to charge you with an offence relating to obscene language."

Answer 3

I've seen it done.  Just the other night actually at my local railway station.  They ignored the woman that did it.

But I don't think it's a smart move and there will probably be a law against it if they decide they aren't going to take it.
