What specific acts of hospitality did Dev offer to his guests, including the disguised Sai Baba, and what was Dev's initial thought about the uninvited Sanyasi?

During the Udyapan, Dev respectfully performed several acts of hospitality for all his guests. Chapter 40 notes that after the meal, the rituals of Uttaraposhan (final sipping of water) and Shuddhachaman (rinsing the mouth) were completed. He then provided fragrant cool water, Mukhashuddhi (mouth fresheners), sandalwood paste, flowers, betel leaves, perfume, and rosewater. Despite this elaborate hospitality, his perception of the Sanyasi was clouded. His mind only fixed on the thought that "He is some guest who has come to get a meal," and this state of delusion prevented him from recognizing that the Sanyasi was, in fact, Sai Baba.
