How did Sai Baba remind Bhagwantrao Kshirsagar about his family's forgotten tradition of Vitthal worship?

The story of Bhagwantrao Kshirsagar, found in Chapter 4, beautifully illustrates Sai Baba's respect for Vitthal worship. Bhagwantrao's father had been a great devotee of Vitthal, but after his passing, the family worship and food offerings (Naivedya) had ceased. When Bhagwantrao came to Shirdi, Baba, who referred to his father as a friend, revealed that He had pulled Bhagwantrao there for a specific reason. Baba stated that Bhagwantrao was not only keeping Vitthal hungry by neglecting the worship but was also keeping Baba hungry. Baba explicitly said, 'Now I will remind him and put him back to worship,' thus gently guiding his friend's son back to his spiritual duties.
