How a street preacher was called in Uganda?

There are many street preachers in Uganda, holding a Bible in their hands standing around a conner preaching to passengers. Most of them preach in local tribal languages but when they see a foreigner they switch to English. Today I have the honor to sit with one of the street preachers and ask her questions. Her English happens to be not good but with the help of a colleague, we had a good little interview.
