You can't do much about the behaviour but you can keep it in the family. Had it not been for the smoking ban he would have remained in the bar with his fashionable friends and not been exposed to the chance of meeting people who didn't think he was fabulous and, what's worse, might engage him in conversation. These days if you want to find a celebrity don't go looking inside places. Try instead the goods entrance of one of London's luxury hotels or the fire escape outside its most expensive restaurants. They'll be there - probably sans minder - running the risk of rubbing shoulders with chummy from the accounts department and just possibly some patient soul with a video camera from The Sun.
