Sir Paul McCartney shuns fans' requests for autographs - in a bid to enjoy his days off.
The Beatles legend used to feel obliged to give in to his supporters' demands while out and about - but he admits he's now developed a set of rules to protect his privacy.
He tells the BBC, "The weight of fame can get pretty annoying. But you know what I do now? I have rules, I've finally grown up and I finally realise I've got rights. So people will come up to me in a restaurant and say, 'Can I have your autograph?' and I say, 'I'm really sorry but I don't do that when I'm eating. I hope you understand. I'll shake your hand and I'll talk to you.'
"Because I'm quite happy to talk to people on a one-to-one human basis, but the minute they turn me into this celebrity I'm pretending not to be for that minute, I sort of say, 'No, I'm not going to do that.' Most, in fact 99.9 per cent of people, are very understanding because they understand privacy."
And MCCartney warns there's another place where he shouldn't be bothered - in shops.
He adds, "Shopping is another. I say, 'I'm really sorry, I'm shopping and you know what guys are like at shopping, not very good. I'm looking for some nails and they've got to be three inches long for the job that I'm doing, and there's no way I'm going to find them when I'm chatting to you and having my photo taken.'"
