Why was Boss Dharamsee so conflicted about eating the grapes that Sai Baba offered him?

Boss Dharamsee's conflict was multifaceted. Firstly, as Chapter 35 explains, he had a personal aversion to that type of grape, stating "he loved seedless ones" and "had a dislike for these grapes." Secondly, he had a practical health concern, as his doctor had specifically forbidden him from eating grapes without washing them first. This created a dilemma where he felt it was improper to wash a saint's prasad himself. Thirdly, he faced a social and spiritual predicament: he felt it would be disrespectful to reject something offered by a saint, feeling "heavy in his mind to reject them." This combination of personal preference, medical advice, and social decorum created the internal turmoil and "various thoughts" described in Chapter 35.
