Two very hungry German couriers ate a fruit cake destined for a German newspaper and in its place mailed a box of credit card data. The data including names, addresses and card transactions ended up at the Frankfurter Rundschau daily. The mix-up triggered an alarm, and police advised credit card customers with Landesbank Berlin to check their accounts for inconsistencies. Fruitcake must be different in Germany for people to want to use it as something other than a paperweight.
