Can you walk me through the timeline of events that led to Dev's confusion about Baba attending his feast?

The confusion stemmed from a series of events detailed in Chapter 40. First, a Sanyasi visited Dev to collect funds for cow protection. Sometime after this, Dev traveled to Shirdi and invited Sai Baba to his Udyapan ceremony, and Baba promised to attend with two others. On the day of the feast, the very same Sanyasi appeared again. Dev, remembering him only as a fundraiser, told him to come back at noon for the meal. The Sanyasi returned at noon with two companions, ate, and left. Because of the initial meeting's context, Dev never suspected this was Baba in disguise. This led him to mistakenly believe Baba had not come, causing him to write a disappointed letter to Jog.
