It has now become clear to me exactly what it is that they do with those urine samples collected in doctors' offices, for drug testing, and so on. In fact, the additional income corporations and other institutions get for used urine could well be what keeps them (you'll pardon the expression) afloat. I wonder, though, what it's posted under in the accounting offices -- accounts receivable? accounts payable? general ledger? And how do you handle the inventory?
