We don't tend tend to notice or remember most of the people we come across in a given day, but some can really stand out even if we never actually learn who they are.
And while I'll always remember the woman who helped me after I sprained my ankle getting off the bus when nobody else cared, the unfortunate reality is that most of the randos who stick out in our minds have negative reasons for this.
So when we hear about folks getting some sly revenge on the jerks they happened to meet that day, it never fails to satisfy us.
And sure, most of these cases don't matter in the grand scheme of things. But sometimes, they can speak to a problem with serious implications for who don't get their necessarily specific orders taken seriously.
