And how does the QR code get my food from the kitchen to my table? How does the QR code handle a request like "do you have a baby-seat for our 2 year old?", and subsequently point me towards where said baby seat can be found and offer a solution how it gets to my table? How does the QR code resolve the situation that another set of customers already uses said baby seat? How does the QR code resolve the situation that we are 12 people, we all want to sit next to each other in the non-smoking area, but there are only 2 tables there each sitting 5 people? How do I explain to the QR code that there must have been a mixup in the kitchen and what was delivered to me was not what I ordered? How does the QR code deal with unruly customers who harass other guests? How does the QR code deal with a requirement like checking vaccination certificates, which was implemented by law on short notice and not part of the systems original spec?
