I don't have much to go on; my memory is very hazy. I only recall the idea of the story, which is that a city in the future becomes so full of people that they can't have their own kitchens ... There's not enough room, and even if there was, they can't move produce into the city fast enough to distribute it to shopping centers.
The only way people can eat is in huge community canteens, and then only in very strict shifts. If you miss your shift, you don't get to eat until your next allocated shift.
That's all I remember. But I'd love to read it again. Any guesses what the story could be?
