Montenegro has its own kind of Shabbat. A simplified version. In 2019, the country's parliament passed a law that turned Sunday into a sort of mandatory day off for all stores. The only exceptions are gas stations and small kiosks selling beer and cigarettes. The fine for breaking the rules can go up to ten thousand euros.

The main reason behind this move was the authorities' desire to give shop workers more time with their families. The law doesn't apply to cafes and restaurants, so you won't starve. Either way, you can't really reschedule your Sunday grocery run.

It's no wonder Montenegrins are considered the laziest people in the Balkans (sorry for the stereotype, but take it with a grain of salt). The locals themselves have played a role in this reputation, even coming up with their own 10 commandments. Though to be fair, this is relatively new folklore, mostly created to attract tourists.
