How do random strangers behave when you put them in certain set-up situations? It’s the premise of the social experiment. And these tests are rarely bettered than when ABC News‘ TV show ‘What Would You Do?’ sets them up. We’ve seen plenty of great experiments from them before…

Their latest? A scenario testing out how people might react when confronted with a veteran in a store. A Veteran trying to pay for groceries but who quickly discovers that he hasn’t quite got enough cash for it. Will people step up, be counted and volunteer to help out? Or shy away and pretend not to hear and see what’s going on…?

The one to watch out for? The elderly lady. She’s seen and heard the whole thing and does something quite remarkable. If you’re having a bad day, this is guaranteed to restore your faith in humanity, no problem! Watch:
