vet confronts man over coffee size, man laughs mysteriously

A vet inexplicably confronts someone's neighbor about the size of his Dunkin' coffee purchase, making a reference to 'kings' that nobody asked for. The neighbor's cryptic response and subsequent laughter suggests either an inside joke or two unhinged individuals speaking past each other in a Dunkin' Donuts. This reads like an NPC dialogue tree that glitched into surrealist poetry.
