some teachers
When you're a student you have to deal with teachers (or professors, as they like to be called in the higher reaches of the education biz). Some of these teachers provide very strict rubrics for the papers they assign which quantify many details of the ideal paper, including the date beyond which it may not be submitted without loss of points; when they provide this document days later than they promised it makes it more fun. Most people in the class won't mind the delay, having not made any effort to start work on the assignment, but the principle of the thing! As for me, I wasn't procrastinating all day today: I had other important stuff to do!
