Sure, you could walk up to a touchscreen and order your espresso. But I want to ask if the scones are fresh. Or how sweet the iced tea is. Or ask for a sample of something. Or ask for extra sugars. And on and on. And how 'easy' is it? How do you handle changing inventory? Running out of materials? Are you ADA compliant? How many languages do you support? And so on. Go ahead, try to mock up an ordering app for a coffee shop that gets different pastries in each day, have an ever changing offering of beans, and each customer has a very particular set of desires for how their coffee is made. Make it work for the Spanish woman, the blind child, the teenager in a wheelchair. Get it to answer "which pastries don't have eggs in them?"
