Every morning, on her way to the laundry shop she runs in Johannesburg’s Alexandra township, Tsholofelo Mphela stops at a bright yellow shipping container to buy a few spoonfuls of sugar.
Inside, shelves are lined with large jars of beans, rice and maize meal, and clear boxes filled with breakfast cereal and loose teabags. A tap dispenses cooking oil by the millilitre. The cashier weighs Mphela’s purchase before ringing it up for a few rand.
