Why was Boss Dharamsee so hesitant to eat the grapes Sai Baba offered him?

Boss Dharamsee's hesitation stemmed from several internal conflicts as described in chapter 35. Firstly, he had a personal dislike for the variety of grapes being offered, preferring seedless ones. Secondly, a doctor had explicitly forbidden him from eating grapes without washing them first, and he felt it was inappropriate to wash them himself in that setting. This created a dilemma where he found it difficult to eat them but also felt it would be disrespectful to reject a saint's offering. These conflicting thoughts caused him to feel heavy in his mind and initially question the situation.
