How did Sai Baba handle skeptics or those who came with a 'clinical interest' in his abilities?

Sai Baba had a unique way of handling skeptics, as illustrated by the story of Boss Dharamsee. According to Chapter 35, Dharamsee arrived in Shirdi with a critical mind, even questioning Baba's sainthood internally when offered grapes with seeds, which he disliked. Instead of chastising him, Baba was aware of his inner thoughts and turmoil. In a profound leela, when Baba insisted he eat more grapes, Dharamsee discovered they had miraculously become seedless. This personal experience shattered his 'clinical scrutiny' and ego, replacing them with love and devotion. This demonstrates how Baba worked on an individual level to transform doubt into faith, accomplishing his work by stimulating a person's natural disposition and leading them to the spiritual path.
