What about policemen, firemen, doctors, nurses, teachers, bus drivers, tram drivers, priests, waiters, bar staff, hotel receptions, hotel cleaners, taxi drivers, all staff on trains, all staff at airports, pilots and cabin crew, TV staff, journalists, power station and transmission network staff, anybody who works in production facilities that can't be shut down once a week, etc, etc, etc, etc?
Not to mention teachers on school trips, teachers working with weekend students, mountain rescuers, builders (many projects work 24/7), radio workers, breakdown/recovery drivers, chefs, those working on ships (for instance, those that have to work at night selling cheap stuff in Polish waters when the ferries leave for Sweden/Denmark), border guards, customs officers and many many more.
Why are shop workers treated in a special way by Polonius but not everyone else? I mean, according to him...
Everybody, even the godless, need a Sunday off.
So why are border crossings open on Sundays?
