Well, on that point you’d probably hate how we do it in Germany. With small exceptions for restaurants, bakeries, and small shops at train stations and the like, everything’s just closed on Sundays. Although some states allow a restricted number of “open Sundays” per year. But I have to say that while it does make shopping less flexible, it does have advantages, too. It makes sure that almost everyone has a day where they can see their family and where everyone has a day off, even poorer people who might not be able to choose a job as easily and would otherwise be forced to work on Sundays (or just everyday). It also makes sure that almost nobody has to work when there’s an election, which are usually on Sundays.
We are also used to it, and since most people also don’t work on Saturdays that’s mostly the day to run errands for us. But it definitely is a common culture shock or at least a surprise to those who are not used to it.
