Café Pelé: The Contagious Billboard

One of the greatest mysteries of the universe: why is it that when someone yawns, we have the urge to yawn too? What is the explanation for contagious yawning? With the help of a motion sensor, when someone came close to the panel, the actor on the screen started to yawn. When people saw this, it became contagious and they started to yawn too. Then the panel showed a message: "Did you yawn too? It's time for coffee. Café Pele". The cure for this epidemic came with promoters handing out cups of coffee to those people who had yawned.
