Why was Boss Dharamsee initially hesitant to eat the grapes offered by Sai Baba?

According to the account in Chapter 35, Boss Dharamsee had two primary reasons for his hesitation. Firstly, he had a strong personal preference for seedless grapes and disliked the seeded variety that Kaka had bought and Baba was distributing; the text notes, "he did not like that variety." Secondly, he was concerned about hygiene, as his doctor had forbidden him from eating grapes without washing them first. This created a significant internal conflict, as he felt it was difficult to eat them but also felt it would be wrong to reject an offering from a saint, causing him to be "troubled in his heart about how to act."
