I know in Japan for instance, there’s a unmanned store where you can buy things with the only thing meeting you near the front entrance & exit is self checkout. It’s a trust based system where you walk in select what you want (without locking any essential or mundane item behind plexiglass), as in they depend on individuals having common sense on not stealing paying via a “honesty box” based on a honor system.
If there are desperate unhappy people it will probably not go well. Our society produces a lot of desperate, unhappy, people.
And then there are those that are just assholes, and think that someone who trusts their fellow Citizens like that should be taught a harsh lesson.
