At Michigan State, I had a math prof (Wade Ramey) who would lock the door after class started. If you were late, you couldn't attend.
He also insisted students purchase a stapler and staple their homework. And he would give negative points on assignments. You could say "I don't know how to do X" for a step in a proof (0 pts), but if you put in something wrong, you would get negative points on that part.

He was a good prof, and I enjoyed his classes.
