In the Terry Gilliam movie “Brazil”, the late actor Bob Hoskins had a small role as an A/C repairman. He shows up when a citizen has an overheated apartment and it becomes a nightmare of bureaucracy. As an agent of the state, he can ruin lives. It’s a small piece within a wide-ranging film about the evils of modern, oppressive society, but very funny in a dark way.
I remember the movie and the scene like it was only yesterday ;) It was Robert DeNiro who played the repairman:
