What does the anecdote about the Noolkar and Dixit families in Chapter 9 teach about following Baba's advice?

A note within Chapter 9 provides a powerful lesson through the experience of the families of Tatyasaheb Noolkar and Bhausaheb Dixit. Sai Baba had told them to eat a meal at Kopargaon before continuing their journey. When they arrived, the meal wasn't ready, and because their train was due, they went to the station without eating. There, they discovered the train was delayed by an hour and a half, meaning they could have eaten after all. This short story from Chapter 9 illustrates that Baba's instructions, no matter how mundane they may seem, are precise and meant for the devotee's benefit, and that impatience or disregard for his words can lead to inconvenience and missed opportunities.
