But most people would rather do their routine shopping on Saturdays or after work. I don't know anyone who does it on a Sunday.
Well, and I do most of my shopping on Sundays: but, of course, I normally live in countries where this is allowed. In Madrid, mercifully, there were a few migrant stores that ignored the law - I did a disproportionate amount of shopping there.
BTW, and what would a Jew be supposed to do? He cannot shop on a Saturday.
He could on Saturday evening between sunset and 10pm under the Hungarian law Or for that matter go to those stores that would be allowed to remain open.
A bit restrictive, isn't it?
Yes. That's why I favor a blue law like that of Colonial South Carolina. Christian-owned businesses were required to be closed on Sunday, but Jewish-owned ones were required to be closed on Saturday. Still, I doubt anyone will be working 16 hours a day. Even those who keep a Saturday sabbath should still be able to find ample opportunities to shop Monday-Friday.
