What happened on the day Babasaheb Tarkhad forgot to offer the daily Naivedya, and how did he discover his mistake?

According to the narrative in Chapter 9, Babasaheb Tarkhad had committed to offering Naivedya to Sai Baba's photograph daily. His practice was to offer a piece of sugar candy. However, one day, being the chief officer of a large mill, his mind was preoccupied with business, and he forgot to perform the offering in the morning. He remained unaware of his lapse throughout the morning. The discovery came at lunchtime when he returned home and sat down to eat. It was his daily routine to be served the previously offered sugar candy as 'Prasad' with his meal. The cook would place this on his plate as a form of "purification of the food." On that fateful day, when the Prasad did not appear on his plate, he immediately realized that the morning offering had been missed due to his hurry.
