Efficient Fast Food 
By Mike Rappaport 
According to Marginal Revolution: "Who would have guessed that when taking drive-thru orders at a McDonald's it's more efficient to send the order not 25ft into the restaurant but 900 miles away to a call-in center which then relays the order via computer to the workers inside the restaurant making the food." 
As a frequent buyer of fast food (but the healthy kind, with salads instead of french fries and no buns), I can believe it.  I always have a special order and they often make a mistake.
