How did Baba, in the form of a Fakir, provide Appasaheb an opportunity to fulfill his vow?

After Appasaheb declared his intention to give ten Rupees, an opportunity to fulfill this vow presented itself in a unique way. As recounted in Chapter 33, a Fakir appeared before him on the very same day he made the statement. The text poses a rhetorical question, asking why Baba would come in a Fakir's form if not for his love for Appa and as a pretext to collect the promised Dakshina. However, Appasaheb's reaction demonstrates the test he faced; because the Fakir was a stranger, Appa became suspicious and did not offer the six Rupees he had readily available, thus missing the immediate chance to make good on his word.
