What happened when two gentlemen from Goa came to see Sai Baba, as described in the Satcharitra?

Chapter 36 recounts an interesting episode involving two gentlemen from Goa who visited for Sai Baba's darshan. Both men surrendered at his feet, but Baba's interaction with them was puzzling to onlookers. He specifically asked one of the men for a dakshina of fifteen rupees, 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, prompting Madhavrao (Shama) to question Baba about his actions.
