I worked at an art gallery years ago right next to the Hollywood hills, lots of famous people (or assistants) came through to buy art / gifts.
Michael Madsen.
Delivered a large framed piece to his office off of sunset blvd floors up, wrestled that thing up the side stairwell. When it was all over he gave me a shot of something, we laughed then I went back to work.
Richard Roundtree, R.I.P.
Quentin Tarantino
Leonardo DiCaprio, big art guy.
Rodney Barnes
Rondell Sheridan
Jonathan Winters, Funny FUNNY guy.
Rosanna Arquette
David Arquette, pretty cool guy
Courtney Cox
KRS1, big tall dude.
Everlast and Danny Boy.
Steve White, comedian. Another Funny one.
John Tempesta
There are more, these are just the people I remember.
What I can say is despite celebrity status they were all pretty normal (for the most part), what was weird were the people following them around, trying to get something from them to profit from one way or another. They were freaks, literally small groups with walkies tracking their movements, i.e. DiCaprio.
