The words 'matatu tout' leave one with a mental picture of a shabbily dressed man, probably chewing on miraa while hanging precariously from the matatu door. Once in a while he will bang on the side of the public service vehicle while shouting himself hoarse to attract potential passengers.
But a new matatu culture is emerging, where touting is assuming respectable standards. Most matatus plying the Ongata Rongai, Githurai and Eastlands routes are pimped up - giant TV screens, blaring music, Wi-Fi and creative graffiti are the common features.
