There's a Boda Boda under there somewhere (a Boda Boda is a motorbike that serves as a taxi/transport). At least you can nap on the ride home!
A snack for the road? Sometimes at intersections in small trading posts a swarm of vendors, all in smocks, run up to the windows of any stopped or slowing vehicles. They sell anything from water to cooked bananas to chicken kabob things. If you don't roll up your window, expect a plethora of snacking options shoved in through the window.
