Describe the challenges faced by the couple from Akola when they tried to offer khichdi to Sai Baba.

According to Chapter 28, a devout couple came to Shirdi from Akola with the primary intention of offering khichdi naivedya to Baba, a vow inspired by a dream. Despite staying in Shirdi for two months and serving Baba daily, their specific offering of khichdi remained unfulfilled for fourteen days. The text notes that the lady did not like this prolonged delay in her resolved vow. On the fifteenth day, she brought the khichdi at noon, but she faced another challenge: Baba had already sat down for his meal behind the curtains, a time when no one was supposed to enter. Her journey's purpose was at risk of remaining unfulfilled.
