This is what happens when you live in a small town and you don’t go to the movies very often: You are amazed at the new Coke machine in the Malco lobby, with its touch screen and ever-changing video display with enticing buy-Coke-products ads. And then there’s the adjacent candy vending-machine, perfect for creating your own movie-watching snacks. My movie-lobby dream machine? One from Starbucks that lets you brew and enjoy your favorite espresso or coffee drink — or at least get a chilled DoubleShot.
