  An important feature of Walker’s framework is that it allows for trust relations between individuals who have not met, and who will possibly never meet, in person. And in her scheme, trust relationships can occur not only between humans who are unknown to one another, but also between humans and non-human entities such as corporations. Walker illustrates the latter point in an example where someone encounters particularly bad service on an airplane operated by a major commercial airline. She points out that when we have such an experience of bad service, it is appropriate to feel resentment, not necessarily toward specific individuals who work for the airline, but toward the airline itself. So the entities comprising a zone of trust need not be limited to known (human) individuals.
