I alllllllmost remember it being like that in my far away childhood, probably without the Thursdays, though then I didn't care that much since I was a child. Now I think it would be quite a constraint to have no variation in hours. But in my childhood a huge proportion of women didn't work outside the home.
I suppose society benefits with people tending to eat at the same hours, etc. How about grocery type shops, are they closed too?
Adding, if most of the shops are small, it does take another whole range of money and personnel effort to keep open more than, say, eight or nine hours, and many places in the US are 'dark' in the evening and earlier morning for that reason.
