Living in LA, i've actually encountered quite a few famous people, even discounting those Q&A's, book/cd signings or promotional appearances. My one story begins with "John Lithgow bought me a latte." Through college, I worked at Jimmy's, one of the on campus coffee houses at UCLA. We often get actors coming in since the Theater/Film department is nearby, and Hollywood actors/director often give seminars or guest lectures. There were also young actors who attend UCLA. I remember locking eyes with Chad Allen once while walking across campus. Any how, John Lithgow came in and order two lattes. I made them, rang him up. He picked the drinks to leave, then turn back, and gave one to me. He explained that he was meeting his wife and had bought the coffee for himself and for her. As he was about to go look for her, he sudden see that she had already arrived before he did and had already gotten herself a drink. So no, he didn't actually intend to buy me a latte, but technically, he bought one and gave it to me.
