You know, I'm calling from Germany – and we are considered an extremely punctual, systematic and efficient bunch ;-)) We don't just have ticket systems with queue numbers and remaining time displays, progress notifications and status signals at MacDonalds, but also in public administration, citizen service centres, school offices, doctors' surgeries and even at some meat counters in supermarkets... And yes, of course it has advantages: you know from the number you've drawn that you still have two hours to run other errands, etc. Well, if it works. Unfortunately, experience teaches us that, at least in our case, it was a failure. The digitalisation of all these processes will now be just as bad; service quality is getting worse and worse and general frustration is growing infinitely. I hope you tackle the problem and do it right from the start!
