What was the significance of Sai Baba telling Jog to give Cholkar tea with a lot of sugar?

Sai Baba's instruction to give Cholkar tea "well-filled with sugar" was a deeply significant and personal confirmation of His omniscience. As Chapter 15 explains, Cholkar had passed an exam by Baba's grace and vowed to distribute sugar candy. Due to a delay in visiting Shirdi, he secretly gave up sugar as a personal sacrifice. When he finally arrived and was a guest of Jog, Baba's specific words about the sugared tea were a direct acknowledgment of Cholkar's private act of devotion. Baba did not even drink tea, so the instruction was clearly not for Himself. This leela served to amaze Cholkar, bring tears of joy to his eyes, and firmly establish his faith. It was a clear message, as Chapter 15 states, that his "vow of sugar has been accepted, And your rule of renunciation is also complete."
