Sign my petition !

A person is waiting for customers in front of a supermarket. This person is here to convince them to adhere to a special cause... The first customer is a twenty-year-old man who first refuses politely but who rapidly loses patience... The second customer is a fifty-year-old woman who first sounds hesitating but who ends up signing the petition.

Just to show you how students work together ! (20 seconds only !)
