As an occasional DHS client, I partly agree, but there's one crucial thing they severely fucked up in the new layout: the "client" has no idea when "someone" will come fetch them. So you get an intensely frustrated mob of people waiting off to the side, wondering if they'll be stuck there for 10 minutes or three hours, and straining to hear when every few minutes one of the geriatric case workers shuffle over and mumbles horrible mispronunciations of random last names. Which means you can't work, can't listen to music or concentrate on anything, really, just sit on the edge of your seat.
Compare with the normal take-a-number bank queue system, when you have a fairly good idea of how long it will take to go from "now serving 123" to "your queue number is 567".
These are not exclusive, you can have both. In fact, last time I had to visit an administrative office they had an open office for the employee workspaces with numbered desks and a traditional waiting area with a take-a-number queue system (well, actually an online appointment booking system) that directs to you a specific desk if it's your turn.
