When in the 60’s i first heard about the Sunday thing in Germany I coukdnt believe it, no car washing, no lawn cutting, no diy, no clothes hung out, no loud music, what did they do all day? Though it makes for a quiet and relaxing day. They still keep to Sunday’s as we used to years ago, no shops open to this day, as is the case in most of Europe I would think. Certainly in France. Families would go out for a walk dressed in their Sunday best ( remember that?) and have ice cream or coffee and cake. They may well still do this. Probably not as much....
I do my washing on a Sunday but avoid shopping if I can because I feel staff should be able to be at home with family instead of having to be at work especially As many large supermarkets are open 24 hours a day. We managed before with Sunday closing, plus a half day closing midweek, but that is all long gone. I am not religious but Sunday is now exactly the same as any other day, apart from the roastie of course.
