What happened with the Dakshina when Kaka Mahajani and his friend visited Sai Baba, and how did it affect the friend?

The situation with Dakshina was quite pointed during the visit of Kaka Mahajani and his friend. As Chapter 35 recounts, after the friend had already bowed, breaking one of his vows, Baba asked for Dakshina but specifically only from Kaka Mahajani. Later in the afternoon, when they were preparing to leave for Mumbai, Baba again requested Dakshina, this time asking Kaka for a specific amount of seventeen rupees. Crucially, Baba asked nothing of the friend on either occasion. This deliberate exclusion made the friend, who had originally vowed not to give any Dakshina, feel "restless in his mind," highlighting a further shift in his internal state from defiant skepticism to a longing to participate.
