What were the specific events that transpired when the Sanyasi and his two companions ate at Dev's house?

Chapter 40 details the Sanyasi's visit for the meal. Having been told to come at noon, the Sanyasi returned exactly on time with two others. Dev seated all three, and they were 'thoroughly satisfied by the meal.' After they finished eating, Dev respectfully performed all the concluding rituals, including Uttaraposhan (final sipping of water), Shuddhachaman (rinsing the mouth), and offering fragrant water and mouth fresheners (Mukhashuddhi). Despite serving them personally, Dev remained unaware that it was Baba in disguise, viewing him only as a guest who came for a meal.
