Right after the Professor agrees with Luke that “no child should be unable to talk with their father”, he tells luke that if there’s anything he wants to talk about he’ll always be ready to listen…
This is the best AITA because on the actual matter at hand I'd say he's kinda right (ish), $4900 for a week of work is really good money and they can always celebrate later. He should have obviously talked it over with her first but still. What makes him an asshole (or just like, a really really weird person) is every other detail that is tangentially mentioned.
