How did Sai Baba first arrive in Shirdi and who was the first person to call him by that name?

According to the introductory chapter of the Sai Satcharitra, the young Maharaj arrived in Shirdi as part of a wedding procession for Chandbhai's wife's nephew. The procession stopped near the Khandoba temple, where he met a man named Mhalasapati. Upon seeing Maharaj, who was wearing a kafni, cap, and dhoti, Mhalasapati greeted him with the words "Aavo Sai Baba" (Come, Sai Baba). As Chapter 0 explains, Maharaj held onto this name for the rest of his life, even stating in a legal testimony that "They call me Sai Baba."
