If you had the opportunity to sit down and have lunch with Warren Buffett, what would you ask him? Turns out, most don't even ask about investing.

The annual charity auction for the opportunity to have lunch with Warren Buffett closed with another record breaking final bid on Friday night. Within the auction's final hour, bids jumped from $1 million all the way to the winning, record-breaking big of $3.5 million dollars. All of the proceeds from the auction go to San Francisco's Glide Foundation.

Buffett says most of the questions he gets during the lunch aren't about investing, which makes enough sense considering the winner has to be able to pay over $1 million afford to sit down with Buffett in the first place. One past auction winner wowed Buffett enough to earn himself a job, at least. Ted Weschler paid over $5 million to win the 2010 and 2011 auctions, and impressed Buffett enough during their dinners that he was hired to help manage Berkshire Hathaway's investment portfolio. 

We suspect for this year's winner, who wished to remain anonymous, it's mostly about the good will and good food.
