居い候そうろう三さん杯ばい目めにはそっと出だし

expression

a freeloader hesitantly asks for a third helping of rice

Proverb describing how a long-term guest or dependent, after initially being reserved, eventually becomes bold enough to ask for more, often used to illustrate the gradual loss of modesty when one gets too comfortable.

• 「居い候そうろう三さん杯ばい目めにはそっと出だし」というから、最さい初しょは遠えん慮りょしていても、慣なれると図ずう々ずうしくなるものだ。

  As the proverb goes, 'a freeloader hesitantly asks for a third helping of rice' — even if you're reserved at first, you get bold once you get used to it.
