What does Chapter 29 tell us about the group of devotees from Madras who visited Shirdi?

Chapter 29 narrates the story of a group of devotees from the Madras region (now Chennai) who came to Shirdi for Sai Baba's darshan. They were on a pilgrimage to Kashi and stopped at Shirdi on the way, having heard of Baba's fame as a generous and great saint. The text specifically mentions a family of four within this group: a man, his mother-in-law, his wife, and his daughter. This family belonged to the Ramdasi sect and performed devotional singing with great enthusiasm during their stay. According to Chapter 29, their experience with Baba exemplified his unpredictable nature; he sometimes gave them money, sometimes a sweet, and at other times sent them away empty-handed, demonstrating that his actions were not bound by any fixed rule.
