I'm thinking of Tesco in particular here but it applies to plenty of things.
Tesco is in my mind because they always said that they had staff there anyway, stocking shelves and cleaning the warehouse and whatever, so why not stay open?
What changed that over Covid, did they realise that they didn't actually have to have the staff doing that stuff so they just stopped opening?
