This is Not the Dew You're Looking For

What's worse than a vending machine that's out of Mt. Dew? A self-service vending station that has an entire cooler full of Mt. Dew, scans the bar code of the Mt. Dew, correctly identifies the Mt. Dew, adds the Mt. Dew to the order and asks you to pay... then say's "The selected product could not be found. Please return to shelf or cooler". What the what?
