VO: "This man has just moved. He's changed his phone number... his post-code number... his license plate number..."

VIDEO: The man doesn't remember his new door-code. He gently asks to an old lady to let him in. But the grandma thinks he is a thief and sprays some teargas in his eyes.

VO"... that's why - at Société Général Bank - we won't change his bank account number on top of that."
