Regarding the story of the two visitors from Goa, what was Madhavrao's (Shama's) specific reaction to Sai Baba's handling of the Dakshina?

The incident with the two gentlemen from Goa is detailed in Chapter 36. When Sai Baba accepted fifteen rupees from one man but rejected an unsolicited thirty-five rupees from the other, it caused great surprise among the onlookers. Madhavrao, also known as Shama, was present at that time and personally witnessed this event. Seeing what he perceived as partiality, he directly questioned Sai Baba about the reason for his differential treatment of the two devotees, seeking to understand the logic behind the action.
