That would be a dream for autistic people with heavy sensory issues. Mine are usually manageable, but it sure would be convenient either way. I’ve never seen any 24/7 supermarket over where I live; I guess it’s just not a thing in my country (or Europe in general, from my experience).
Surely there are some people that prefer the night schedule. The problem is capitalism and wage labor, not the fact that there are “inconvenient” schedules for most people.
