Most of the time around these parts, you would have to pay 160 cents for most canned drinks when you buy them from a vending machine.
However, vending machines, commonly located at someplace busy like a transport hub sell any can of drinks for 100 cents. What irks me more is that places like executive convention centres or even conference venues possess those kind of vending machine. The kind of people who frequent these places hardly ever find the need to drink carbonated drinks from a vending machine considering they are more inclined to drink either alcohol, coffee, or even plain water.
But yeah, pertaining to Muppo's minor predicament, it would bug me off as well.
