Have you ever had that craving for coffee so strong that your yawns cannot be accounted for? Douwe Egberts, a South African coffee company agrees that most of the people who yawns need a wake up beverage and it had to be their coffee. So they install a rather interesting coffee machine at the O.R Tambo International Airport. The demand for coffee here is extremely high and through the use of this machine, many had a chance to try the coffee. All they have to do is, YAWN at it. Yes. Just open your mouth and yawn and the machine would immediate dispense coffee for you. It is that easy and it is FREE. How neat is that? The machine is equipped with face recognition and it will know when you are actually yawning. All in all, this “Bye Bye Red Eye” machine has rewarded 210 yawns with their coffee. And what it receives in return is yawns and lots of smiles.
