"Put down that wrench!"

I hear stories of students being disruptive in ways I only ever imagined happened at school, and was personally given shit by another student last year after I asked student A who had persistently failed to do any preparation including group work to leave a small group tutorial. I think we're seeing not only people unfitted to HE doing degrees, but also a result of the break down of educational authority at school level (one small point is that I really dislike the way Sheffield students automatically adress me by first name. if they asked I'd say yes: but it shouldn;t be assumed.)
