I have this from volume 4 of the manga

>Also, it felt a little weird that the first time we saw that old man (outside of ep 1) was him reflecting on all the times he'd had with a character we'd never seen him interact with? What was up with that

They are shown interacting in ep 5, but you can barely tell Dr. Adatara is infuriated by Makabe's antics.
But yeah, they didn't adapt a chapter from the manga that leads to the award ceremony, where the three shop owners (Adatara, Makabe and the Chief editor of CITY mag) mess with the old guy.
