According to some news fresh from The Cophenhagen Post, in Hillerod, Denmark, an electrician recently looked at his bank account and discovered there had been a rather significant withdrawal. The bank had accidentally taken out 63 billion kroner from this man's account, which according to the online currency calculator I used, is $11 billion dollars.
They apparently didn't argue the point.
It turns out that they had typed in an account number where they should have typed in the numbers for a withdrawal--3,200 kroner from a mortgage deed registration on a property deal. But instead, the bank took out an extra 63,002,842,493.
They quickly replaced it, and I'm assuming that the bank didn't give the man anything for his shock, like a pillow or an all-inclusive vacation at a nearby resort. And maybe they shouldn't have. It was, after all, an honest mistake. But, of course, if it had been the electrician who had made a careless error, the bank management wouldn't be laughing and letting bygones be bygones. He would have been given enough overdraft fees that he'd be rotting in debtor's prison now.
