This wasn’t too different in the adaptation. Mrs Tance actually has some lines in the manga, while she has remained silent in the anime. In the anime, she also does not accompany her husband to meet the Governor when they return to the surface. But only this one page of fluff was really left out completely.
It does make Mr Tance feel more like one of the greedy people that he is lamenting here. But the way he talks the governor into supporting the adventurers and paying them well, is still there.
