I work at a university (support staff) and your story is precisely why I have always refused to take students papers. Now it's not such a big deal with computers but back then I would tell the professors, "if you want students to hand in a paper, you be here, in your office, to receive them. I will not take responsibility for a student's assignment because it's the student's word against mine and the student will always win." A student could 'say' they handed it in to me but actually didn't. And at the end of the day, it doesn't matter to me if said student passes the class or not and it's not up to me to make sure their assignments get handed in to the right person. [/rant]
