Of all the things that never happened, this incident never happened the most.
I don't know, it might not be far from the truth.
When they claim they spontaneously came up with the perfect comeback to shut up a stranger in a waiting room or checkout line, yeah, I'm skeptical.
But a claim that they contacted a person's employer over something trivial, in the hopes of getting that person fired, or to feel more important? I totally believe they would do something like that. Worse things have happened.
