Developments:

The local STD clinic ran out of drugs on Monday. It's now Friday and there is still no sign of new supplies. This is not an unusual occurrence. Drugs often arrive late from the central distributor in far-off Pietermaritzburg, so clinics order more than they need to tide them over until the next batch comes. The central distributor is aware of this practice, however, so he sends less than what the clinics ask for. The clinics, in turn, factor the distributor's cunning into their orders, which they inflate still further. This week, it seems, the distributor emerged victorious, with patients, of course, the unwitting victims.
