Can you narrate the incident involving the two gentlemen from Goa as described in the Shri Sai Satcharitra?

Certainly. Chapter 36 recounts an episode where two gentlemen from Goa came for Sai Baba's darshan. Both men surrendered at his feet, but Baba's interaction with them was quite distinct. He specifically requested and accepted a Dakshina of fifteen rupees from only one of the men. However, when the second gentleman offered thirty-five rupees of his own accord, Sai Baba immediately rejected the offering. This apparent partiality was perplexing to everyone present, including Madhavrao (Shama), who proceeded to ask Baba for an explanation.
