Ah, along with the mysterious 'Stop Smoking' stall. Is it a front for Scientology? I've not investigated. It looks fun!...and we found the UK Communist party in the centre of Glasgow doing a little bit of campaigning.
I passed that stall recently...I can't remmeber if it was Central station or outside Borders. They asked me if I'd like to stop smoking instantly. I said no and walked away before they could say any more.
I can never shop in peace without someone selling me something.
