Bad ones on the other hand make you buy their badly photocopied, handwritten notes from the university copy center, where the receipt is itemized as:

Binding and printing: $1.50

Royalties to professor X: $$

I literally changed majors back in my school days over those shenanigans by the department head.

At least the university copy center is open about it vs taking the blame themselves for ridiculous printing fees.

I would expect better from Professor X though.
