I had one truly awful professor in college. I’m pretty sure he came in hung over multiple times. Regardless of speculation, he definitely DID Google the topic of the say and get notes from other professors from other universities to teach from and then also had the audacity to complain about them. The cherry on the shit cake was him fall asleep during the grad students’ presentations and then was weirdly aggressive and nit picky about what they said after waking up. I really laid into him on the student review. Supposedly their boss reads them all. I hope he saw some consequences. It’s one thing to sort of be hands off and say “you’re in college now, you need to teach yourself,” but it’s another thing to be an asshole and disrespect your students by falling asleep.
