A family in Nagpur runs a chain of chemist shops. The first one is opposite a large hospital. The others are in residential colonies, near a market and beside a busy children's clinic. Each shop has a pharmacist in charge who orders from the stockists and handles the cash. The owner visits each shop when he can, and every month his accountant puts the figures together.
In the rains, the shop beside the children's clinic runs out of a fever syrup and an antibiotic suspension again and again. The pharmacist orders more, and the stockist sometimes has none. Parents go to the chemist next door. At the same time, the market shop has plenty of the same syrup, ordered for a scheme the stockist offered. Nobody puts the shops side by side.
At the end of the year, the owner orders a clean-up of every shop. Each pharmacist fills a carton with expired strips, syrups and creams. Some of it goes back to stockists. Some of it nobody will take. The accountant shows a healthy sales figure for the year. The owner looks at the cartons and wonders how much of his profit is sitting in them, and how much more is still on the racks.
