It’s known, in the game, as a picture opportunity.

Politician on the make meets constituent/kiddie/moviestar/public figure, hands are grasped, big smiles, cameras whir, flashes pop and the happy little circus moves on.

Sometimes, it doesn’t work so well. The kiddie bursts into tears. Sometimes, it’s a bust. The movie star’s smile is so radiant the politician may as well have stayed in bed.

And then there’s the day the Treasurer, Josh Frydenberg, met the royal commissioner, Kenneth Hayne.
