The only times I asked for a picture was with Joe Royle at a sportsman dinner and Kilbane when he came to Barrow for football focus when we reached the 3rd round of the cup a few years back. Mark Lawrenson was there as well (he was a late replacement for Paul Ince) but ran away as soon as the show stopped filming.
My Sister was working for the club at the time and said Kilbane and Dan Walker were really really nice, Lawrenson was a miserable t**t.
When I have seen the odd player on the street, etc. it would feel so weird just to go up to them and disrupt their day, they could be doing something normal but important, etc. My mate said that he was sat a few tables away from Fellaini in a restaurant and although busy chatting to his friends/family and eating, people kept on going over, it is just plain rude, in my opinion.
