I heard Sai Baba didn't ask for Dakshina from Kaka Mahajani's friend, even though he asked Kaka. Can you explain that part of the story?

Yes, that is a significant part of the narrative in Chapter 35. After the friend had already broken his first resolve and bowed down, the matter of his second resolve—not to give Dakshina—was addressed in a unique way. On two separate occasions that day, Baba asked for Dakshina specifically from Kaka Mahajani. The second time, he requested a precise amount of seventeen rupees from Kaka. However, the text explicitly states that Baba "asked nothing of the friend." This act of being ignored when it came to Dakshina made the friend feel restless in his mind, highlighting Baba's omniscience regarding the man's original intentions.
