What is the story of Boss Dharamsee and the grapes from Shirdi?

The story of Boss Dharamsee, detailed in Chapter 35, is a beautiful leela of Sai Baba. Dharamsee, a curious but skeptical visitor, was in the mosque when Baba began distributing grapes that a devotee named Kaka had offered. Dharamsee disliked that they had seeds and was hesitant to eat them. He thought a true saint would know his preference. To his surprise, Baba gave him even more. Troubled, Dharamsee held them in his hand until Baba said, 'Throw them in and eat.' Upon obeying, he was astonished to find the grapes were completely seedless. As Chapter 35 narrates, this miracle shattered his 'clinical scrutiny,' and love for Sai was born in his heart.
