Madina is a suburb of Accra, but in many ways it still feels like the city. In the market area there are the same long rows of sellers sitting behind tables piled high with fruits and vegetables, cans of tomato paste, biscuits. There are big wicker baskets full of red palm nuts. People are calling out the prices of their goods: "Thousand, thousand!"

I was walking down such a row of tables, carrying a black folder full of questionnaires. The task was auditing. It's one of my favorite parts of the job. The idea is to verify the data collected by the field workers and to make sure they're giving out accurate information to potential loan clients. Practically it means sitting down and talking with people.
