back in my 20's when I was a waiter and bartender:
Bill Gates and his wife, father, and mother in law
Jeff Bezos and his wife (very down to earth and genuine people every time)
Steve Ballmer (was not at all excited to meet him, did not actually talk to him other than what he wanted to order)
Cindy Crawford (drool, drool, and more drool) fuck she was hot back then
Mike Nichols (famous director and wife to Dianne Sawyer) He was very kind and warm.
While in Los Angeles:
Jessica Biel and her dog "East". She is naturally gorgeous and very genuine
Mark Harmon (I worked on Navy NCIS for a while and met the entire cast). He was a very respectful person to everyone on set.
Thomas Ian Nicholas from American Pie. I worked on a music video of his and also worked on the photo shoot for his wife DJ Collette. Both of them are very kind, down to earth, and genuine people. Nice couple.
Mariel Hemingway and her present husband. She is wonderful and very approachable. They are a beautiful couple.
Arnold Schwarzenegger and his family.
Sprague Grayden from the TV show 24 and Jericho. Very cool and actually spent quite a bit of time talking to her on many occasions.
Danny Treo but who has not met this guy
Jennifer Garner (totally down to earth)
Lisa Bonet and that dude from Game of Thrones (beautiful couple, real people)
Pamela Anderson (always a scowl on her face, looked like a fucking bag lady). I never actually spoke to her so she does not count but I did not speak to her by choice because she was so fucking gross in the way she talks to people. Fuck her.
Jenna Jameson of course! (when she was still hot)
From Tyler Shields parties: That chick from Californication with the great set of tits who was 16 when Hank fucked her, that gay guy from InSync who has not yet come out of the closet (so obvious he is gay and he was with another obviously gay guy at the party, actors from American Pie and similar C and D list celebs that I really do not know.
Also that guy from Seinfeld who had a Pakistan themed restaurant. I think his character's name was Badu or something like that.
There are many others who I was in the same room with but never actually talked to.
