So many, many years ago in school we did Taco Bell on the way home from last call.
There was one of the exchange students there, too. He ordered a 7 layer burrito and a beer. The cashier had to tell him with a tortured look "We don't sell beer here, sir."
The fella kind of tilted his head, glanced around the place and confusedly replied, "You mean all these people are here for the food?"
