I think HK people have the least amount of patience when it comes to waiting for good food. A lot of it is that there are so many good food options to choose from, so who needs to wait? Besides most all restaurants take reservations. I can’t remember waiting for longer than 30 mins anywhere in HK because in a city like HK, the time=money rule is probably most evident and visceral. (Just watch what HK people do even before the “fasten seat belt” sign goes off on any CX flight! And don’t even get me started on the ensuing footrace to immigration.)
