How was Dakshina handled when Kaka Mahajani and his skeptical friend visited Sai Baba?

The matter of Dakshina was a key part of the story detailed in Chapter 35. Kaka Mahajani's friend had vowed not to give any Dakshina. During their first visit, Sai Baba asked for Dakshina, but only from Kaka, not the friend. Later that afternoon, when they went to ask for permission to leave, Baba again requested Dakshina. Once more, he only asked Kaka, this time specifying, "Give me seventeen rupees." Baba asked nothing of the friend on either occasion. This pointed exclusion caused the friend to feel restless in his mind, completing the humbling of his initial skeptical stance.
