Can you describe the incident where a Fakir approached Appasaheb Kulkarni and what happened with the Dakshina?

This story from Chapter 33 describes how Appasaheb, after finally encountering a Fakir he had been searching for, was asked for Dakshina. Appasaheb gave rupees one by one, first for himself and then for his friends, totaling six, and then three more at home, making nine. The Fakir was still not satisfied. Appasaheb then explained he only had a ten-rupee note left. The Fakir took the note, surprisingly returned the nine rupees he had already collected, and departed. This interaction is presented as an example of how Sai Baba works to fulfill the words and promises of his devotees.
