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).
We used to have them in the UK pre-covid. My local Tesco and Asda were all 24 hour, except for Sunday trading. Now, barely any are open around that time.
