Fair enough. I'm sure it's happening in nearly all large metro areas in developed nations. I only said that because I hadn't noticed this trend (at least not to this extreme degree) in the course of visiting other large metro areas in the US.
There's also obviously the separate fast-food and fast-casual markets that focus on rapidly cycling customers with minimal delay and much lower service levels; they still try to be full as much as possible which still means queuing at peak times, but the queues tend to be shorter in time or just as deep (or deeper), and tend to involve actual physical, rather than merely logical, queues.
