What promise did a devotee named Cholkar make to Sai Baba, and what was his reason for doing so?

According to Chapter 15, a devotee named Cholkar came from a poor household and his livelihood depended on making his job permanent by passing an examination. Facing this challenge, he made a vow to Sai Baba. He humbly resolved that if he passed the exam by Baba's grace, he would present himself at Baba's feet in Shirdi and distribute sugar candy (khadisakhar) in His name. This vow was a firm resolve made in the hope of securing his job and overcoming the financial instability that plagued him, as failing the exam meant his 'daily bread was at stake'.
