“The vending machine just steals your money.”

I came with the solution! This year i made a Vending Machine program based on a Finite State Machine for some obscure subject at uni.

I should have called it SmartSodaVendor, as it knew better than you that you surely want a large cola and that you would pay 8 monetary units for sure so it should give you 3 units change in advance!

Such an inovation, much change, very soda😃

Hang a sign on it that says:
