Unfortunately Whitebear, because Nanny has decided it is naughty to smoke indoors now, people will smoke in the street, and thankfully (not becuase I'm a smoker - I'm not - but because I'm sick of the erosion of our freedoms) there is absolutely naff all anybody can do about it.
As for this lady, I'm very much in two minds because (a) they were smoking on an open air platform, so they weren't doing any harm, so in that respect I can't help thinking she was an interfering busybody, but (b) it is the property of the rail company so they are entitled to decide what can and cannot happen on their property, and (c) what they did was wholly inappropriate - telling her to mind her own effing business is one thing (and I can't help feeling somewhat justified) but pushing her on to the rails was disgraceful - and as Ethel has said, they pushed her a day or two after she had confronted them, so it kind of smacks of premeditation.
I saw the lady interviewed on the SE news last night, and I've got to say, she did come accross as one of those annoying women that would stick their oar in to things that have got nothing to do with her - not that that is an excuse for what happened to her.
