Coca Cola, working with McCann Madrid, placed this special ATM in several different streets in Madrid in the run-up to Christmas 2012. Users were presented with the on-screen message 'Get 100 euros. Without your card'. In other words, free.
The 'Cashpoint of Happiness' added: 'But only if you agree to share it'.
The ATM then gave some suggestions as to how to share it. Hire a storyteller for children in your neighbourhood, buy some nappies for a pregnant woman, buy breakfast for your office colleagues, and other ideas.
When you agreed to the terms, your video was taken.
Coca Cola's video shows that a number of people did indeed do some good with the money, delighting various people.
