Teens Bullying Boy At Burger King, Don’t Notice Man On Bench

This man hasn’t quite figured out the clue yet. He looks confused and angry at the manager and the employee. It seems like he’s about to explode when he hears a cry for help from the bullied teenager behind him, the penny finally drops. The man lowers his eyes and turns around. He seems ashamed of himself. 

He mumbles something while trying to avoid eye contact with anyone nearby. A similar reaction seems to spread to certain other customers.

And the rest of the customers with a “bullied” Whopper?
