Upon arriving in Cog Nation, you take the elevator of the Cogs, Inc headquarters to floor 100, the Chairman's floor. You walk into his office and see none other than The Chairman. For the first few weeks, you handle secretarial duties, like taking notes. One day, The Chairman asks you to get him some lunch, as he is growing older and has a hard time getting down to the cafeteria. You hear him ask for "pota...s" but you can't decipher what he said. Checking the cafeteria menu, you see two items that match what he ordered before his voice gave out; Potassium-41 and Potato Fries. You have to bring him one, but you know he will be angry if you screw up his order. Which one do you bring him?
