I've probably shopped at Walmart less than 10 times in my life. It's probably because they aren't conveniently located for me. But also they have so much bad press that I just don't want to be associated with it. At the same time, I also have the feeling that this will never happen to me so I'm indifferent.
That indifference is a bug in our society. It allows this injustice to be farmed out to 3rd party law shops using a system designed by corporate lobbying dollars to harass powerless individuals. Walmart isn't indifferent and they are mildly evil so the world is made worse by their presence.
