I heard him say to a crowd that one should feel free to walk up to him if one sees him in the barbershop and say what one thinks.

I absolutely would do so if I saw him on the street.   It's absolutely possible, by the way, since I live near him.

My wife once saw him sitting in traffic.

He read to one of my son's in preschool and was very, very, very gracious to the other when we ran into him at a science fair.

He is the best politician ever to represent me - and I don't agree with all of his policies by the way.
