They say time is money. If you’re name is Warren Buffett, your time is very, very expensive. A couple years ago, the third wealthiest man in the world decided to hold an auction where the proceeds would benefit the San Francisco-based Glide Foundation. What was he auctioning off? Himself. For $2,630,000, an anonymous bidder and seven of his friends won the opportunity to attend lunch with the legendary investor at NYC’s Smith & Wollensky steakhouse. Big money talk.
