Back in the day working on the line:
Jack Nicholas - nice guy, got his autograph.
Eddie DeBartolo Jr - always nice and polite, great tipper, gave tickets away.
Former Oakland A's owner (late 90s) - friendly, polite guy, gave tickets and hats.
Garth Brooks... my first day off in 21 days straight he came through. I wasn't there but heard about it later. One of the line guys' sister was a huge fan, so he asked one of Brook's crew if he could get an autograph for her. Garth showed up and got on the plane, his crew closed the door to go, but then Garth opened the door and came down to sign his autograph for him.
Caddying golf tournaments in college:
Jason London (Randy Pink Floyd from Dazed and Confused), Jimmy Vasser, Dick Butkus, Jack Lemon, Don Cheadle, Dennis Farina, Alice Cooper, and many others I'm forgetting - all cool, down to earth guys.
Bernie Mac, didn't say much to anyone, but wasn't rude to anyone.
The guy who played Al from Tool Time, couldn't stop talking about himself the entire time.
Joe Carter from the Blue Jays, wouldn't stop talking about how much he won at the casino the night before, how they basically gave money away, then stiffed me on the tip.
Flying 121:
Kareem Abdul-Jabbar was nice and friendly, while his wife was not to the FAs.
Richard Petty another nice friendly guy.
Danny Glover super nice, down to earth guy, happy to talk to anyone or take a photo with anyone.
