Women selling food at a Tazara train stop. Ben Mack /
"Ndizi!" the women balancing enormous plates and bowls on their heads would shout in Swahili, meaning they were selling fresh bananas. "Maembe!" others would say, meaning they were selling very ripe mangoes. You could usually buy a bunch for about $0.40 by simply passing money through the window — and it was really quite something to see the women walk around, balancing everything perfectly on their heads without using their hands or having to walk slowly.
