This is one of the infamous chapas - a local bus that held far more people that it should have. We actually passed on this one because we didn't feel like cramming in - which of course seemed strange to the operators.
We used these to travel around town. A few times when we weren't on the route, we took a taxi. The fare is 7.5 meticais, which is about 25 cents in US currency. They collect the money at the end, and sometimes you have to pay a little extra or a little less, because no one carries .5 meticais.
