Why did Sai Baba appear in the form of a Fakir to Appasaheb, and what does this reveal about Sai's nature?

According to the narrative in Chapter 33, Sai Baba appeared in the form of a Fakir to Appasaheb as a pretext to test his devotion and collect the Dakshina he had promised. Appasaheb had verbally committed to giving ten Rupees but then hesitated when a strange Fakir appeared. The text poses a rhetorical question: if Baba had no love for Appa, why would he come in a Fakir's form? This implies the act was born of love and a desire to help the devotee fulfill his word and be free from spiritual debt. It reveals that Sai is capable of granting the worldly and spiritual desires of any devotee with undivided faith and would go to great lengths, even changing his form, to engage with them.
