Canault did indeed come to Mamy Restaurant for his meals occasionally. It was just two meals a day.
He was busy with the church's matters in the morning, and he couldn't come and line up, so he settled his breakfast simply.
As a missionary who was pursuing his interest, and had to inherit hundreds of millions of fortune if he quit being a missionary, he still preferred a carefree lifestyle. Chaos City was good. He could go home if he missed home, but he could keep a good distance normally. He was carefree and happy.
Everything was great in Chaos City, but for this picky chowhound from Rodu, his biggest torture here was that he couldn't get to eat great food.
This had once been one of the biggest reasons why he hesitated between going back home to inherit his family's fortune and staying put.
And the appearance of Mamy Restaurant was just like a ray of light in Canault's world. It gave him ample reason to stay.
