Has a total stranger ever shouted you a coffee? It's rare, but it happens.

On the border between Victoria and New South Wales, however, the 'pay it forward' movement has been taken to a whole new level.

Kindness of a stranger: John Kennedy Jr (right) paid for Tyson Crawley's petrol after he could not pay.

Tyson Crawley, a 30-year-old carpenter from Albury, was on his way to work in the early hours of Friday morning when he stopped at a petrol station to fill up his ute and jerry can.

With a couple of iced coffees tucked under his arm, he approached the station's service desk, only to realise he'd recently transferred all his money to a new account and had forgotten the PIN for his new bank card.
