Before visiting Shirdi, what were the specific conditions that Kaka Mahajani's skeptical friend set for the trip?

According to Chapter 35, Kaka Mahajani had a friend who was prone to doubts and a firm devotee of the formless, being averse to idol worship. His visit to Shirdi was driven by "clinical curiosity." He laid down two very specific conditions for his friend, Kaka Mahajani, before agreeing to make the journey. The friend stated, "We will go to Shirdi and only take the Darshan of the saint; We will never bow our heads, nor provide any Dakshina." He made it clear that he would only accompany Kaka if these two stipulations were agreed upon before they set out from Mumbai.
