Gateux be! Namasa be! Sogo be!
(cakes for sale! Bananas for Sale! Meat for sale!)
Anyone who has travelled on a Mali bus has heard this call, when the bus stops and a crowd of insistant young merchants swarm into the bus with an assortment of goods they hope to shift in the minute or so the bus stops. Bananas, cooked sweet potatoes, little packets of roasted mutton wrapped in paper from old ciment bags and many other commodities.
