According to the text, why were grapes brought to the mosque and what was Dharamsee's initial attitude upon arrival?

The source material from Chapter 35 states that it is considered improper to go 'empty-handed to the door of God, a priest, or a Guru.' Following this custom, a man named Kaka purchased two seers of grapes with seeds, as the seedless variety was unavailable, to offer to Sai Baba. Upon arriving at the mosque in Shirdi with Kaka, Boss Dharamsee's initial attitude was not one of devotion but of skeptical curiosity. He immediately questioned another devotee, Babasaheb Tarkhad, asking 'What is here? Why do you come?' and mentioning that he had heard reports of miracles. This shows he approached the situation with a 'clinical scrutiny,' seeking proof rather than having faith from the outset.
