Shake Shack Scraps Cashless Store Experiment

For many years, the customer experience at fast-food and fast-casual restaurants didn't change much. A diner had two choices: Wait in a line of people inside the restaurant to order from a human, or wait in a line of cars at a drive-through to place an order through a speaker. But now, the industry is evolving at a rapid clip, with options for ordering at unmanned kiosks, via apps, or on websites growing increasingly common.
