Can you explain the story of the Madras group's offering to Sai Baba and what they received in return?

A group of devotees from Madras gave an offering, a bafri of two rupees, to Sai Baba at the masjid. In return, Baba gave them two rupees worth of pallav, or offerings. While they did not receive much money back, Chapter 29 explains they received abundant blessings for their journey. Baba told them, "Allah Malik bahut dega (Allah, the Master, will give much)" and "Allah tumhara achha karega (Allah will do good for you)." These blessings ensured their pilgrimage was completed without any hardship, demonstrating that Sai's grace was more valuable than monetary gain.
