Sex for 20 bob in a matatu

First, a bob is the equivalent of a penny in U.S. currency of 100 units per dollar or schilling in Kenyan currency.  Twenty bob is about twenty-five cents.  Second, a matatu is a van used for transport between towns.  It has seating for 12 but most often carries closer to 25 or more.  Often sitting in each others' laps or some other awkward and sweaty position.  This, combined with the frequent bumps in the road, results in a rather unique experience.
