Describe the scene involving the two gentlemen from Goa and Sai Baba's unusual request for Dakshina.

Chapter 36 recounts a scene where two gentlemen from Goa came for Sai Baba's darshan. Both men approached and surrendered at his feet with joy. In a perplexing move, Sai Baba asked for a Dakshina of fifteen rupees from only one of the men, which that individual gave happily. However, when the second gentleman tried to offer thirty-five rupees on his own initiative, Sai Baba immediately rejected the offering. This peculiar and seemingly partial behavior astonished everyone who was present at that time.
