Since the university where I work is right next to the main train station, most of my Swiss-watching (pun very much intended) takes place in the station. The Swiss are interesting, particularly when it comes to weapons in public.
It’s common to see guys with slung SIG SG 550′s walking around the train station as they head off to military training, the range, etc. Nobody pays these guys any mind whatsoever; it’s just part of what’s normal here.
I admit to doing a double-take when I saw a guy with a slung katana picking up some groceries in the main station, but nobody else seemed to care. “Guy with a sword getting a liter of milk and some eggs. Meh.”
Even rather unusual things, like the guy wearing a full-body ghillie suit with a rifle slung on his back buying a cup of coffee from the McDonalds, go completely unremarked-upon by anyone here. It’s amusing to think of Swiss Wookie-suiters being a thing.
