Can you narrate the incident involving the two gentlemen from Goa who visited Sai Baba?

Certainly. According to Chapter 36 of the Shri Sai Satcharitra, two gentlemen from Goa came for Sai Baba's darshan. Both visitors surrendered at Baba's feet and were filled with joy. In a curious interaction, Sai asked for Dakshina of fifteen rupees from only one of them, which the man gave with joy. However, when the second gentleman offered thirty-five rupees of his own accord, Sai Baba immediately rejected the offering. This apparent partiality surprised everyone present, including Madhavrao, also known as Shama, who then questioned Baba about his actions.
