Related to this, but in a completely different context, I have had similar thoughts lately when eating out at restaurants in Spain. It's incredibly frustrating from a customer's point of view when the waiter taking your group's order has to use a newfangled tablet or phone-like device and tap through each individual order, often depending on the peculiarities of the app's UI and how the designers expect the process to carry out: “Are you all having the set menu? No? OK, first I need to know how many of you are having it?" [taps count on screen] "Right, now I need the starters but ONLY for the set menu orders..." etcetera—you get the idea. Then, while going through this unnecessarily slow process, God forbid someone who ordered from the set menu wants to change their main while the waiter is already taking the à la carte orders.
Meanwhile, in restaurants that haven't unnecessarily techified the procesz, the waiter can take the order in the way that's most practical given the circumstances and that best fits his way of taking notes. Ah, but then how does the order reach the kitchen without the tech? I have no idea, all I can say is that it worked fine before these things were put in place, and the manual system is by far the quickest and most flexible from a customer's point of view.
