In the story of Boss Dharamsee and the grapes, was anyone else's experience with the fruit mentioned?

Yes, the account specifically contrasts Dharamsee's experience with another devotee's. According to Chapter 35, the grapes Kaka brought as an offering had seeds, and Baba was distributing them to everyone in the mosque. Another devotee, Babasaheb Tarkhad, was also present and received the grapes. After his own miraculous experience, Dharamsee asked Tarkhad what kind of grapes he had received. Tarkhad confirmed that his grapes did, in fact, have seeds. This confirmation made Dharamsee 'extremely surprised in his heart,' reinforcing the personal and profound nature of the miracle Baba had just performed for him alone.
