What is the story Baba told about being robbed by a Brahmin, and what was the lesson?

In a story from Chapter 36, Sai Baba recounted a time when he was wandering by the seashore and was invited to stay in the mansion of a wealthy Brahmin. Despite the host's seeming hospitality, the Brahmin robbed Baba of thirty thousand rupees while he slept. Heartbroken and grieving, Baba remained on the veranda for fifteen days. He was then approached by a Fakir who advised him to seek out another specific Fakir for help and, crucially, to renounce his favorite food until his money was returned. Baba followed this advice, met the other Fakir, recovered his wealth, and thus learned a powerful lesson about faith, surrender, and the efficacy of making a vow or sacrifice to achieve a desired outcome.
