Oddly enough a mate of mine many years ago had a very similar (though less fiscally rewarding) experience.
I left him outside a shop while I nipped into get something and on coming back out I found him in state of extreme head-fuckery.

He says he was standing facing the shop window peering in, with about a foot of space between his face and the window glass when he descibes being hit smack in the middle of the face really hard by a single pound coin. He says it came straight on flat-and-level right out of no where. He is certain there was no possibilty it was thrown by anyone from behind him and bounced off the window as A: there was no sound striking the glass and B: on turning round there wasn't a sinlge soul within near sight. All quite odd really.

this is the real reason the economy is fucked.
it's Quantum Indeterminacy in action. The economists have measured the amount of money in the system to such a level of precision that cash is quantum tunneling out of bank vaults into random locations.
