I've met him twice, one at a fundraiser where he was most likely paid to be there. Took a lot of time to speak to everyone, seemed genuinely likeable and was actually quite funny.
The other time he was eating with his family and friends in an Italian restaurant in Swinton, where incidentally he has a pasta named after him on the menu (!) - and quite a few families were in with little kids wanting to get a little momento signed or have a picture - he was totally unbothered by it and took time to say hello to everyone.
I was once in Wings in Manchester City Center when our former No.10 came in with his Mrs. After they were disturbed once they put a screen around their table and staffed it with waiters so you couldn't go near them. That's what I would call being a tool.
