In the Simpsons episode “Secrets of a Successful Marriage” Homer gets a job teaching at the local civic center. On the way to his first day of class, he stops at the drive thru of Krusty Burger. When asked for his order, Homer said he had no time because he had a class to teach. The teenager working the drive thru informed Homer that it’s a felony to tease the order box. I wonder if it’s a crime to go to the drive thru, not order anything, and drive away.
Oh, come on… Nothing stops the order boy from answering things like “Very well, Sir, that would be 20 $, now please proceed to the next window!”
In the end, it costs Homer his time, he has got no food, and nothing else has happened.
