People never ask for autographs for themselves, it's always 'for my wife' or 'for my mum' or something.
When we used to be play at the Dell my daughter would wait behind for autographs whilst I fetched the car. I must put in a good word here for Gary Lineker who spent a good 30 minutes making sure everybody got his autograph. Also Arsenal under George a Graham and even Man Utd with Sir Alex were very considerate.
