I'm not sure I believe that math though. The person taking the order is also the person responsible for the drinks and the payment. Most of the inside is already done through app and kiosks. Drive through also has the ability to pick up app orders. The drive through order taking isn't the big cost here. You would still need that person to hand food, prep drinks. The real time is in prepping the order not taking the order. Reason for the line at the drive through is the meal prep not the ordering process. If AI slows down the ordering process in any way it is actually a net negative.
