Apple CEO Tim Cook Isn't a Cheap Lunch Date

— -- The chance to have lunch with one of the most influential CEOs in the world doesn't come cheap.

Bidding is underway for a chance to have lunch with Apple CEO Tim Cook at the company's Cupertino campus, along with two tickets to an Apple keynote event. This is the fourth time Cook has offered himself up as a lunch date, with the proceeds going to the Robert F. Kennedy Human Rights advocacy group, of which he is a board member.

With nine days left to go, bidding is already up to $125,000 for an hour of face time with Cook for the lucky winner and a guest.

Last year, the lunch went for $200,000. The year before it went for $330,000.

If you think that's expensive, it's only a fraction of what deep-pocketed bidders have paid for the Glide Foundation's annual charity lunch date with Warren Buffett.

The Oracle of Omaha has commanded bids of more than $2 million in previous years.
