What made Dev suspicious when the Sanyasi returned to Dahanu, and what did the Sanyasi ask for instead of money?

Dev became suspicious because the Sanyasi returned to Dahanu much earlier than he had been told. Dev had previously instructed him to come back after two to four months, but the Sanyasi reappeared in a tonga after only about a month. As chapter 40 details, this premature return caused Dev to doubt the Sanyasi's intentions, wondering if he had forgotten their conversation. When the Sanyasi came to Dev's house, instead of asking for donations for his cow protection fund, he surprised Dev by saying, "I haven't come for money; today we want a meal," also mentioning he had two companions with him.
