Well, you think the person described in the story is a troll because nobody is that unreasonable, right? You’re wrong. People really are that unreasonable. Not everyone whose words are incompatible with their actions is faking to try and trick you. Most people, like you, have some kind of made up excuse why it’s okay for them to act contrary to their own beliefs. Like the state of public transport. I’m sure the person in the story has an excuse just like yours.
