Can you recount the incident involving the two gentlemen from Goa and the offering of Dakshina as detailed in the provided text?

The text from Chapter 36 narrates an incident where two gentlemen from Goa came for Sai Baba's darshan. Both men surrendered at his feet, but a peculiar interaction occurred regarding Dakshina. Sai specifically asked for fifteen rupees from only one of the men, who gave it with joy. However, when the second gentleman offered thirty-five rupees of his own accord, Sai Baba immediately rejected the offering. As the chapter notes, this apparent partiality caused great surprise among everyone present, prompting Madhavrao (Shama) to question Sai about his actions.
