Who questioned Sai Baba about his different treatment of the two men from Goa, and what were the specific amounts of money involved?

The person who questioned Sai Baba's actions was Madhavrao, who is also referred to as Shama in the text. As Chapter 36 recounts, Shama was present during the incident and, seeing the apparent partiality, asked Sai to explain his reasoning. The specific amounts of money involved were fifteen rupees and thirty-five rupees. Sai Baba requested and accepted fifteen rupees from one of the gentlemen. The other gentleman offered thirty-five rupees on his own accord, but Sai Baba immediately rejected this offering, which is what prompted Shama's inquiry.
