How does Chapter 35 demonstrate Sai Baba's omniscience through the grape incident?

Chapter 35 provides a clear illustration of Baba's omniscience. When Boss Dharamsee was given grapes with seeds, he was internally conflicted. He disliked them, felt it was difficult to eat them unwashed, and even thought, 'If he is a saint, how does he not know That I do not like these grapes?' Baba knew every one of these thoughts. In direct response to Dharamsee's inner turmoil and doubt, Baba gave him even more grapes. Then, when he commanded him to eat them, they were found to be seedless. Dharamsee himself realized this, thinking, 'Knowing the intent of my mind...Whatever Sai gives me, they turn out to be seedless and beneficial.' The incident, confirmed by Tarkhad whose grapes remained seeded, was a direct, personal response to Dharamsee's unexpressed thoughts, proving Baba's all-knowing nature.
