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

The leela of the grapes is a beautiful story of transformation detailed in Chapter 35. A devotee named Kaka brought grapes with seeds as an offering to Baba. When Baba began distributing them, a visiting skeptic named Boss Dharamsee was hesitant. He disliked seeded grapes and was also concerned about eating them unwashed. He even thought to himself, 'If he is a saint, how does he not know that I do not like these grapes?' Knowing his thoughts, Baba insisted he eat them. When Dharamsee finally obeyed, he was astonished to find the grapes were perfectly seedless, leading to the collapse of his ego and the birth of profound faith in his heart.
