One of Bernstein’s student said the professor on August 18 — the first day of his psychology seminar — instructed all students to wear a mask during the lesson. “No mask, no class,” read a message at the front of the classroom.

Bernstein tried to explain to the student that he had underlying health conditions like Type 2
diabetes
that make him more susceptible to harsh COVID-19 symptoms.

But the student still wore her mask incorrectly, and minutes into the seminar, Bernstein quit.

“That’s it. I’m retired,” he said, according to a student quoted in the newspaper.
