But all the letters came back, with one exceptions, because of the address label and the invoice matched the receiver. The one exception is a statement to Singapore – this was addressed to the correct recipient.

“This is really weird,” says the head of the post office, when she hears from the mess with the bills. “There were so many different ways, the bills wrong einzutüten. But there are only six different combinations in which such a thing happened as here.”
