Vending Machine Justice

Well i have always had a kind of love hate relationship with vending machines, since you never know if its going to pop out something it holds or is just going to eat up your money. Although you dont see too many of them in India(which makes me glad, since it means employment for a person), there were far too many I came across in the UK and a far too many ate my money. They are virtually ubiquitous vending everything from chips(crisps for my english friends!) to contraceptives. Anyway back to the story, as I said, many a vending machine had failed me or rather deceived me. So one night, I was really hungry after a few unusually rare hours of study at the library. Deciding to get myself a chocolate, I said a prayer to all the gods of vending and popped in a coin and pushed a button. It started whirring and made some ambient noises of providing me with the promise of a snack. Being already skeptical and prejudiced against vending machines, i pushed the button again. What happened next was not earth shattering by any measure, but it dropped two chocolates, not one and I was sure i put in the price for just one. Needless to say I was thrilled. So I tried the same thing next night with the same result. I took it as redemption for the times i was wronged by these diabolical machines. This led me to conclude that when it comes to vending machines, what goes around, comes around twice.
