While there are still a large number of vending machines lacking the ability to take a credit card as payment, one machine in Singapore gives you an additional option: hugs.
It is as it sounds. Just walk up to the machine, which says "Hug Me" in Coke-font, embrace it, and you get a Coke. The machine has been so popular, they'll be soon popping up all over the rest of Asia.
Who would have thought a machine that dispenses free soda would be popular?
