Can you explain the story of Bhagwantrao Kshirsagar and why Sai Baba brought him to Shirdi?

The story of Bhagwantrao Kshirsagar, found in Chapter 4, illustrates Sai Baba's respect for Vitthal worship. Bhagwantrao's father was a great devotee of Vitthal and a friend of Baba's. After his father passed away, Bhagwantrao neglected the worship of the family's Vitthal idol, ceasing food offerings and other rituals. Baba stated that he "pulled" Bhagwantrao to Shirdi because he was the son of his friend. Baba then revealed the true reason: "He never offers food (Naivedya); he keeps me hungry too. He keeps Vitthal hungry too, that’s why I brought him to Shirdi." Baba's intention was to remind him of his duty and restore the worship.
