I read something about Appasaheb making a promise to give money to Sai Baba. What was the promise and did he keep it?

The provided text from Chapter 33 explains that Appasaheb felt that a single Rupee given by his family to the Fakir (Sai Baba) was insufficient. He declared that had he been there, he would have given ten Rupees. This became his unspoken vow. However, the narrative reveals his struggle with fulfilling this promise. When a fakir, believed to be Baba in disguise, appeared on the very day of his declaration, Appa became suspicious. Despite having six Rupees available at that moment, he hesitated and did not offer the money, thus failing to fulfill his word and remaining in "debt."
