Australian credit card company NAB wanted to reward Australians for being such an honest people, so they set up a fun candid camera prank to test their honesty

Outside the steps of a mall, they placed a pair of sunglasses on the ground. When one of the good Samaritans returned the glasses, the person at the desk took their name who then secretly passed that information along to others in mall.

In moments, signs and TVs all over the mall showed the good Samaritan’s face and name along with much praise for being honest.
