Can you explain the story of how Sai Baba fulfilled Laxmichand's desire for khaja?

In Chapter 28, we learn that after arriving in Shirdi, Laxmichand and other devotees were served some khaja as Baba's prasad on the first day. The next day, Lalaji (Laxmichand) remembered the sweet, and the desire for it remained in his mind. On the third day, a devotee went to the masjid to ask Baba what naivedya to bring. In a display of his omniscience, Baba specifically requested, "Bring me a plate full of khaja; then do the arati-puja." Later, after the arati, Baba announced to all the devotees that he felt like having khaja prasad and that everyone should be served as much as they wanted, thus miraculously fulfilling the unspoken desire that was lingering in Laxmichand's mind.
