How did Sai Baba's method of receiving Dakshina differ between the incidents with Karnik and Appasaheb?

The accounts in Chapter 33 show that Sai Baba employed different methods to receive Dakshina, each tailored to the devotee and the lesson. In Karnik's case, the acceptance was forceful and direct. Narsing Maharaj, who felt like Sai himself, suddenly grabbed Karnik's wrist and demanded, 'Give my Rupee.' The text even clarifies that the Rupee was 'pulled by force.' In contrast, with Appasaheb, the approach was more of a test of a prior promise. Baba came in the guise of a 'stranger' Fakir as a 'pretext for Dakshina.' This was not a forceful taking but an opportunity for Appa to fulfill his word, an opportunity he unfortunately missed due to suspicion. This shows Baba's versatile and purposeful interactions with his followers.
