Who were Sai Baba's earliest devotees mentioned in Chapter 0, and what forms of service did they offer?

Chapter 0 introduces Sai Baba's earliest devotees in Shirdi as Mhalasapati, Kashiram Shimpi, and Appa Jagle. After Mhalasapati welcomed Baba into the village, he introduced him to his companions Kashiram and Appa, and all three became his total devotees. The text mentions they were already known for serving saints who came to Shirdi. The Introduction in Chapter 0 provides specific details about Kashiram's service, noting that he served with his body, mind, and wealth. He stitched a green kafni and cap for Baba, took a vow to provide chillum, tobacco, and firewood for the Dhuni, and would even offer his entire money bag to Baba.
