What information does Chapter 29 provide about the group of devotees from Madras?

Chapter 29 recounts the visit of a group of devotees from the Madras region (now Chennai). These travelers were on a pilgrimage to Kashi and stopped at Shirdi to have Sai Baba's darshan, having heard of his fame. The text mentions they belonged to the Ramdasi sect and performed devotional singing with great enthusiasm, attaining peace in Baba's presence. As described in this chapter, Baba's interaction with them reflected his unpredictable nature; he gave them eight rupees and eight annas, sometimes offered them sweets (bafri), and at other times sent them back empty-handed.
