Who is the person that questions Sai Baba's actions after he rejects a devotee's offering?

The person who questions Sai Baba's actions is Madhavrao, who is also called Shama. Chapter 36 of the Shri Sai Satcharitra details an event where two gentlemen from Goa visit Sai. Baba accepts a 15 rupee offering from one but rejects a 35 rupee offering from the other. This act of apparent partiality was witnessed by Shama, who was present at the time. The text explicitly states that upon seeing this, Shama questioned Sai about the reason for his decision, which puzzled everyone in the Dwarkamai.
