Evidently there were/are several of these in Chester but the local council are planning to remove them as 'some people might be offended by them'. Maybe they're offensive to those with no sense of humour?
Well, Chester is my nearest city, and I shop there regularly, but I've never seen one of these signs. Somehow I think they're an urban myth, or even an urban mythter One thing Chester does have far too many of is tourists......yes I know there's great history there, and beautiful buildings, but when I have to fight my way through throngs of camera toting tourists just to get to my favourite cheese shop....aaarrrggghhhhh
Reminds me of the plaque on a bench in Kew Gardens: "In memory of woman's first name and surname, who loved this place, and her husband man's first name, who didn't."
Juggernaut apparently only 5 plaques have been found so far and they were in places where the council wanted to discourage anti-social behaviour with new local legislation. The signs were a protest against the changes because the protesters thought the council was really trying to target the homeless and vulnerable people. There were two well supported petitions too. This was last October BTW. (I looked it up to read about online).
