The author of Sai Satcharitra mentions a personal story about not visiting a Saint in Bandra. Can you explain what happened?

Certainly. In Chapter 21 of the Sai Satcharitra, the narrator, Hemadpant, recounts his own experience to illustrate how good fortune is necessary to meet a Saint. While he was serving as a Magistrate in Bandra, a famous Siddha named Pir Maulana lived there. The Siddha's servant, Inus, repeatedly urged Hemadpant to come for a visit. However, as the chapter details, Hemadpant's ego and thoughts about his own prestige made him resist, and he never went. He later reflected that this was a result of his own "ill-luck" and that without God's grace, even proximity to a Saint is not enough to secure a meeting.
