When I was in Amsterdam I was with a group of acquaintances of a friend who lived there. One of them offered me an extra piece of pizza they had when I showed up. When the bill came, they asked me for the exact percentage of the bill that that piece of pizza cost. First time experiencing something like that.
I also offered to buy several people a drink while I was there. This was received every time with suspicion and I was treated as if I was trying to gain something transactional besides a simple friendship in the moment. It was an interesting part of that society to experience.
Nordic social norms like this get made fun of all the time by westerners and southern Europeans. A lot of people will take the crappy socioeconomic situations of non Nordic countries just so that they can have warm relations with their families and a culture that doesn’t hate loud noises.
