It doesn't have any plot. It's you masturbating philosophically across a table to yourself who is masturbating back at you from the other side of a slightly warped looking glass then resolving it without actually resolving anything. It's an essay disguised as a story through the constant reappearance of a waitress to fill beer mugs faster than anyone can drink them to provide the illusion of setting and time progression. Plato would have at least drawn a moral conclusion.
