You know what I never see? Vending machines full of ice cream.
I think making ice cream vending machines more prominent and more widely available would make the world a much better place to live. Why fight or be unhappy when you can just go and get an ice cream?!
I'd be happy with either machines that sell prepackaged ice cream treats like you'd get from an ice cream man driving around in one of those ice cream trucks that plays the same song ooooover and oooooover, or a soft-serve dispensing machine similar to a coffee vending machine.
