After Makutsi types up her report, why does she not tell Badule immediately?

Since Mma Makutsi doesn't have a driver's license, her uncle drives her to the Badule house. They wait and watch and follow Mma Badule when she leaves the house to go to a house on Nyerere Drive. They wait for the maid's lunch break so Mma Makutsi can talk to them. She learns of Mrs. Badule's affair and that she is referred to as the town wife. The man has a well-to-do wife who lives in the village of Mahalaype. The man told the maids they would lose their jobs if they told his wife about Mrs. Badule. The maids say the boy is the son of the man and not Mr. Badule.
