Can you tell me the story about Boss Dharamsee and the grapes? What was the miracle that happened?

The story of Boss Dharamsee illustrates Sai Baba's omniscience and power. According to Chapter 35, Dharamsee was a curious visitor who doubted Baba's abilities. When Kaka Tarkhad offered grapes, Baba began distributing them. Dharamsee disliked these grapes because they had seeds and were unwashed, which his doctor had forbidden. As he mentally questioned why a true saint would force these upon him, Baba gave him even more. Finally, Baba commanded him to eat the grapes he was holding. When Dharamsee obeyed and put them in his mouth, he was astonished to find they were completely seedless. This personal miracle shattered his skepticism and replaced it with devotion.
