Just when you thought you have seen it all you come to the Interspar at Vienna Main Station on a Sunday and you'll find a supermarket divided into two separate supermarkets, with separate entries and cashiers, for no apparent reason.
I ended up having to buy peanuts in one shop and water in the other one.
Looks like the reason is that shops in train stations are only allowed to open on a Sunday if they are not larger than 80 m^2.
It feels great to be back in the EU 🤡
