How did Boss Dharamsee's attitude towards Sai Baba change during his visit?

Initially, Boss Dharamsee's attitude was one of skepticism and what Chapter 35 calls "clinical scrutiny." He was full of personal dislikes and doubts, even questioning Baba's abilities when offered grapes he didn't like. The experience with the grapes, however, caused a profound transformation. After obeying Baba's command to eat and discovering the seeded grapes had become seedless, his entire state of mind was stunned. According to Chapter 35, his ego dropped away, his previous resolves vanished, and a deep love for Sai arose in his heart, solidifying his eagerness to return to Shirdi.
