I'm new to Sai's teachings. Why was Boss Dharamsee so troubled by the grapes Baba offered him, and what happened?

The story from Chapter 35 provides a great example of the internal struggles one can face. Boss Dharamsee was troubled for a few reasons. Firstly, he had a strong personal dislike for grapes with seeds and preferred seedless ones. Secondly, a doctor had forbidden him from eating unwashed grapes, and he felt it was inappropriate to wash them himself in that sacred space. This created a conflict: he didn't want to eat them but also felt it would be disrespectful to reject a Guru's offering. As his internal doubt grew, Baba gave him even more. Finally, when Baba commanded him to eat, Dharamsee obeyed and was astonished to find the grapes were perfectly seedless, a miracle that instantly changed his skeptical heart.
