Why did the Sanyasi's return to Dahanu make Dev suspicious, and what was the Sanyasi's actual request upon his return?

Dev became suspicious because the Sanyasi returned to Dahanu in a tonga only a month after being told to come back in two to four months. According to Chapter 40, this premature return made Dev wonder if the Sanyasi had forgotten their previous conversation. However, the Sanyasi's request was different this time. Instead of asking for money for his cow protection fund, he explicitly stated, "I haven't come for money; today we want a meal." He also mentioned that he had two companions with him, shifting his purpose from fundraising to seeking hospitality.
