Could you describe the experience of the devotee who was initially skeptical of Sai Baba and had an issue with the grapes?

Certainly. Chapter 35 details the story of Boss Dharamsee, who visited Shirdi driven by curiosity and a clinical mindset. When Baba began distributing grapes with seeds, Dharamsee was immediately conflicted. He disliked that variety, his doctor had forbidden him from eating unwashed fruit, and he felt it was a problem from the very beginning. His skepticism grew to the point where he thought to himself, "If he is a saint, how does he not know That I do not like these grapes?" This internal conflict and doubt were central to his initial experience at the mosque.
