Q: How do you majorly piss off someone behaving badly?
A: Hold up your smartphone camera to them.
Why does this infuriate them? It’s simple. They’re embarrassed. You don’t even need to be videoing them – just the notion that their bad behavior might be on the front page of a newspaper is embarrassment enough.
Moral of the story: Always conduct yourself as if all your actions were to be printed on the front page of a newspaper. Said another way: Integrity is how you behave when you believe nobody’s watching.
