(This was back when the movie "Catch Me If You Can" came out. The movie poster has two large blue arrows pointing in different directions.  A man buys a ticket and goes down the hallway to the theater. We see him again, walking the other way and looking angry. Finally, he comes up to the counter.)

Me: "May I help you, sir?"

Customer: "Yes, where are you showing this movie?" *waves
the ticket in my face*

Me: "Just down that hallway, sir…the second door."

Customer: "Don’t give me that! I followed the arrows on the poster, and they led me to the bathroom and then a closet!"
