Based on the text, what was Sai Baba's unique practice regarding Dakshina?

According to Chapter 14, Sai Baba had a distinct practice of asking for Dakshina, or an offering, from everyone who came for his darshan, regardless of their religion—be they Hindu, Muslim, or Parsi. The amount was not fixed and could range from a couple of rupees to hundreds or thousands, as He pleased. The text notes that He might even tell someone to take a loan if they claimed to have no more money. Interestingly, He would also command a great millionaire to go ask for Dakshina from a poor person. Baba explained this by saying, "our only one is Allah," and that if a devotee gives him one quality, he gives "a hundred qualities in return," suggesting a spiritual exchange rather than a purely material one.
