Right - thats it. Sorry...that's it. The missing or misplaced apostrophe has irritated one Bristol grammar stickler so much that he has set about correcting and cleaning up public signs in the city. He's anonymous and works in the early hours of the morning. He takes great care, working with specially designed kit, and so successful is he that shop-owners don't even notice when their signs have been put right. The BBC's West of England correspondent, Jon Kay, has been following our man as he works. This is The Apostrophiser's Tale.
