Can you describe the group of devotees from Madras mentioned in Chapter 29 and their experience with Sai Baba?

Chapter 29 recounts the story of a group of devotees from the Madras region (now Chennai) who were on a pilgrimage to Kashi. These devotees, who belonged to the Ramdasi sect, had spent the year in devotional singing and stopped at Shirdi for Sai Baba's darshan. Their experience illustrates Baba's unpredictable nature. The text mentions that they performed their devotional singing with great enthusiasm. As described in Chapter 29, Baba's response to them varied: sometimes he gave them eight rupees and eight annas, at other times a sweet called a bafri, and on some occasions, he sent them away empty-handed, demonstrating that his actions were never fixed or predictable.
