Can you explain the incident involving Madhavrao, Shama, and the request for fifteen rupees Dakshina?

Yes, Chapter 18 recounts this event. After the narrator finished the story of the Bhagavat reading, a gentleman named Madhavrao arrived with a message from Sai Baba for Shama. The message was a direct instruction from Baba for Shama to provide fifteen rupees as Dakshina. Upon hearing this, Madhavrao was extremely surprised. Instead of giving the money, he cleverly replied to tell Baba 'namaskar' as his form of Dakshina. The messenger wryly noted that 'fifteen namaskars were received.' Baba also instructed Madhavrao to sit and talk with Shama, showing his interest in fostering connection among his devotees.
