Hmmm, maybe I had bad examples, my point was that we rely a lot in our daily life that other people do their job right and that even if they don't there will be checks in place that catch problems.
We even rely on organizations and parties to lobby for our interests.
So we kind of accept that we need to rely on other people.
I probably should have said "We relay that the people in the restaurant know how to cook and keep their ingriedients clean and fresh and we rely on checks that catches mistakes"?
