I was watching a video from two years ago about different social norms and this showed up. Found someone questioning the same eight years ago on reddit (when it seemed less normalized). It feels so weird not being aware of this shift, even as a foreigner.
I was a little lost too for the first few weeks I lived in France. Equally, when they said things like “il (n’)y a pas de quoi” which I had to figure out on my own. I finally just straight up had to ask someone after asking for a lighter and thanking them.
