Warren Buffet is so famously rich that his name has almost become a by-word for fabulous wealth or opulence. You probably expect that he met his wife Astrid Menks at a high-society ball, or some exclusive party that regular people would never be invited to. He didn't, though.
When Menks met Buffet, she was his waitress at a restaurant he was eating in. That was back in the 1970s. Buffet, 16 years older than his wife, was rich even back then - but not the multi-billionaire he is today.
