Douwe Egberts unveils vending machine that rewards yawns with free coffee

Douwe Egberts looked to help people in need of a caffeine fix in a campaign, which saw a coffee machine installed in an airport.

The coffee company thought that people at an airport are more likely to be tired than anyone else, so rewarded 210 travellers with a free coffee.

The coffee was dispensed automatically when it sensed the person in front of the machine yawn.
