Who were Mhalasapati, Kashiram Shimpi, and Appa Jagle, and what was their initial role in Shirdi before becoming devotees of Sai Baba?

According to Chapter 0, Mhalasapati, Kashiram Shimpi, and Appa Jagle were three notable residents of Shirdi. Mhalasapati was a goldsmith by caste and a devout follower of Khandoba. It was he who first called Maharaj 'Sai Baba.' Before Baba's arrival, these three men had a practice of serving and looking after the various saints, Gosavis, Bairagis, and Fakirs who frequently passed through the busy village of Shirdi. They would provide hospitality to these holy visitors according to their capacity. This pre-existing dedication to serving holy men laid the foundation for them to become total devotees of Sai Baba.
