The vending machine up the hall decided today not to give me any change. Nothing special there, but just this once I had my phone in my hand and decided to call the 1-800 number to report it faulty… Deadly seriously, all my details were taken, details of the fault with the machine, then a promise to have it seen to, then a promise to send me my change in the mail! I wonder how much it costs XYZ vending company to process a single payout of $1?
