In the story of Gosavi's journey to Jamner, who was the Tangawala and why did Gosavi become suspicious of him?

During Gosavi Bapugir's journey to Jamner, he was accompanied by a Tangawala (horse-cart driver) sent by Nana Chandorkar. Chapter 33 describes this driver as very capable. However, when they stopped to rest and eat, Gosavi, also referred to as Ramgir, became suspicious of the driver. The text from Chapter 33 states that he harbored suspicion because the driver's beard was in the "Muslim style," which made him question who would prepare their meal. The Tangawala had to reassure Gosavi by revealing his identity, stating, "I am a Hindu Gurwala Kshatriya by birth; I am of Rajput caste," and confirming that the food was provided by Nana, thereby establishing trust between them.
