dilbert wearing face mask: i ran the numbers, and your plan does not work under any reasonable set of assumptions.
boss wearing face mask: have you tried "unreasonable assumptions?"
dilbert: why would i do that?
boss: well, to keep your job, for example.
dilbert: our corporate rule is that we won't do business with any vendor who does not give us at least 30 days to pay.
dilbert: but we can get the same product for half the price if we go with the vendor who wants payment immediately. should we make an obvious exception here or be morons?
boss: i think you're under-valuing the moron options.
