What challenges did the devout couple face when trying to offer khichdi to Sai Baba in Shirdi?

After being inspired by a dream, a couple journeyed to Shirdi with the specific vow to offer khichdi naivedya to Baba. According to the account in Chapter 28, they stayed in Shirdi for two months, serving Baba daily, but their main purpose remained unfulfilled. For fourteen consecutive days, the khichdi they wished to offer was not accepted or the opportunity did not arise. The lady became increasingly anxious about this prolonged delay in fulfilling her resolved vow, which was the primary reason for their entire journey from Akola.
