Singapore is experimenting with drone waiters due to a supposed labor shortage in the service sector. I am all for cool new technologies, but in this particular case I can do without. I actually like the Australian system – you order, get a number or buzzer, and when your food is ready you pick it up at a window. It works just fine. I would save the technology for the ordering and paying part. That would really help with a business lunch, for example, where you are in a hurry and would like to order in advance, then not have to sit around waiting for the check. Combining a sit-down restaurant with online ordering also opens up a lot of possibilities for customizing your order and seeing what other people thought were a restaurant’s best dishes. It should also work well with delivery and mobile food trucks.
