I personally think this whole fantasy exists mostly because coffee shops with many options intimidate right wingers who are deftly afraid of looking stupid socially. It causes a great deal of anxiety in them to see a long list of various coffee options they have no idea how to pronounce because they don't want to admit they have no idea what any of those options are and embarrass themselves socially. Anything that is unknown is a social threat that scares them, because looking like you don't know something is embarrassing and they feel emasculated if that happens to them socially. The MAN knows everything.
Also being forced to learn something annoys them. So the anxiety is rooted in the annoying experience of being forced to learn things. It becomes a core memory, "that time at the coffee shop I was scared of embarrassing myself", and that core memory becomes the foundation of these memes and comics.
That or I'm talking out of my ass idk it's 6am and I just typed out a constant stream of thought.
