My dad does not always seem to grasp the concept of fast food, at least not the part of the process that takes place at ordering time. He arrives at the front of the line as if to a new planet, one filled with wonder, and choices beyond numbering. He looks at the menu as if for the first time, asks many questions, then retracts orders, revises with new ones, makes requests about customizing each thing ordered, then tacks on more items or changes. At a kiosk? Endless new joys, and menus to explore menus!

What I'd like to see is a FIFO system where people who are behind, say, my dad, can order with an app on their own phone or tablet, and if their order is ready, it starts getting made.
