In all of my interactions with rich or famous individuals the common theme is that it’s refreshing when people treat them like a normal person.
I spent an afternoon with a well known athlete in a public setting. He was very gracious in all of his interactions. But even I got annoyed with how often we were interrupted by people coming up to us.
He was used to it and handled it well, but it was obvious it he preferred some privacy.
Another well known actor I play sports with asks me to play with him specifically because I treat him like a regular guy. Other guys at the club fan girl over him and it sounds like he gets annoyed by it.
