An unidentified bidder has won a charity auction for a coffee date with Apple Chief Executive Tim Cook, but it will be a very expensive jolt of caffeine.

According to the Charitybuzz auction site, the winning bid reached $ 610,000 when the auction closed yesterday, with the donation going to benefit the Robert Kennedy Center for Justice and Human Rights.

Under the terms of the auction the winning bidder is entitled to a 30-to-60 minute meeting with Cook at Apple Headquarters on a mutually agreed upon date.
