Can you describe the story of the couple who came to Shirdi to offer khichdi and how their vow was fulfilled?

Chapter 28 of the Shri Sai Satcharitra narrates the story of a devout couple who traveled to Shirdi, inspired by the wife's dream of Baba asking for khichdi. Her husband was an officer in the Post Department, and after his transfer to Akola, they made their way to Shirdi. They stayed for two months, serving Baba daily. However, the lady's vow to offer khichdi naivedya remained unfulfilled for fourteen days. On the fifteenth day, driven by her strong resolve, she approached the masjid at noon. Even though Baba was already having His meal behind a curtain—a time when no one was allowed inside—her eagerness was so great that she did not heed the restriction. She moved the curtain herself and entered to fulfill her desire, demonstrating the power of determined devotion.
