How did Sai Baba address the skepticism and ego of Boss Dharamsee during their first encounter?

Sai Baba addressed Boss Dharamsee's skepticism not through words or arguments, but through a direct, personal experience that dismantled his ego. According to Chapter 35, Dharamsee arrived with a 'clinical scrutiny' and was internally critical, thinking, 'If he is a saint, how does he not know that I do not like these grapes?'. Instead of placating him, Baba intensified the situation by giving him more of the seeded grapes he disliked. This forced Dharamsee into a state of conflict. The resolution came only when Dharamsee surrendered his judgment and obeyed Baba's command to eat. The subsequent miracle of the grapes becoming seedless was a direct response to his unstated doubt, causing his ego to drop away and be replaced by love and firm determination to return to Shirdi.
