Why did Sai Baba appear as a different, unknown fakir to Appasaheb, and what was Appa's reaction?

Chapter 33 suggests that Sai Baba appeared in the form of a 'stranger' fakir to test Appasaheb's faith and resolve. This occurred on the very day Appasaheb had made a private vow to give ten rupees. Instead of recognizing the divine opportunity, Appasaheb's reaction was one of suspicion and hesitation. Despite having six rupees readily available, he did not offer them to the unfamiliar fakir. The text poses this as a rhetorical question, implying that if not for Baba's love and as a pretext to accept the promised Dakshina, why would he appear in this way? This event serves as a cautionary tale about how faith can be tested in unexpected ways and how doubt can cause a devotee to miss a blessing.
