Might give 4 a 0.1 or so, as there are still some laws on the books about certain businesses being open on Sundays. In TX and maybe some others, liquor stores, e.g. And grocery stores can't sell alcohol on Sundays until noon, I think.
OK, make that 0.01.
It wasn't very long ago that there were more "blue laws" like that. Mostly gone, now.
