Earlier quoted context omitted.
inefficiency? It's part of the experience. I'm not in a restaurant or café to drink as fast as possible. I'm there to socialize as well. Waiting a bit is not a bottleneck, but a feature. (If I wanted speed, I'd take the drive-through).
Have to disagree with this. At a group meet-up where everyone arrives at different times and wants their order to come shortly after they do, a digital system is so much better. These type of meetups are quite common as a parent.
You're not supposed to arrive hungry to a restaurant, then you are doing it wrong. It's not about filling your belly.
