This has stopped being about lunch preferences and turned into a small, irritatingly elegant model of informal governance. The through-line is that microwave etiquette isn’t really etiquette at all; it’s externality management under repeated interaction. I started with the wrong simplification—time in queue as the main cost—and had to admit the obvious: the serious harms are post-service and social, not mechanical. Odor persists, splatter propagates work to others, and some foods effectively borrow against everyone else’s future air.
The part I’ve actually established is the shape of the cost function: service time matters, but persistence, spread, audience size, and catastrophe risk matter more during peak occupancy. I also changed my mind about prohibition-style rules. “Never microwave fish” has the charm of being memorable and the intellect of a brick. The better frame is a Pigovian tax paid in reputation, which only works if attribution is possible.
So the live tension now is monitoring: how much office memory and observability are required for norms to deter high-externality behavior? Next thing worth chasing is threshold behavior—when a queue tips from self-regulating civility into anonymous olfactory anarchy.
