Switzerland operates on trust. You go to the car service, you get the work done, you leave, you'll receive a bill in the mail later. There is trust that they do the right work and not overcharge you, and there is trust that you'll pay.
Just be sure to mark everything in the ledger, so the hut warden can replace it easier.
Being that close to nature long enough does things to a person. It's outside of something easily described with any human words.
And yeah, it's a high-trust society. In some farms you'll find a fridge where you can get local produce and leave your payment in the box. Especially so in the mountains where they make their own cheese. You'll find me lugging a nice cut of cheese back home from a Sunday hike. That box will be locked though, because there's more people passing than at a remote cabin :-)
This ethos percolates down, well beyond empowering the minority via direct democracy: its shameful on the individual to not carry one's weight. The smallest unit is the one to trust.
Contrast that to other collectivist societies, with top heavy bureaucracies, where the top literally cannot carry their weight (debt/deficits) and the populace is always looking for the biggest bureaucracy to rescue them.
There's no trust in people, because people are competing to weaponize the large state to screw... you.
Pretty common round here. (in NZ)
Often people just leave remote dwellings like that unlocked and stocked with supplies, sometimes with a signature book and/or donation box. For larger places some people even build a separate cabin next to the main house for travelers to use.
Then I go home to eastern Europe (we call it central Europe back home, lol nobody wants to be branded as east European since it reeks of russian association which for a long time means something very negative) and kleptocracy is visible literally everywhere on all levels of society, its nauseating beyond any tolerance from me... Its impossible for me to accept it once I've experienced much better society. One of the reasons to never move back and not raise kids back there, even if whole family is far (which is not always a bad thing).
Also the fact that most online businesses allow late payment via invoice shipped with the goods feels crazy.
