I used to get students parking in my personal expensive (i.e. $750 over year) parking bay at Uni.
At one stage I had a clapped out mitzi van that I used to park behind them blocking them in - as I was not inconveniencing other drivers I have informal approval by the Uni parking people to do this and would call the parking inspectors to make sure the student got a ticket .
I would also leave a note on their windscreen saying that I lived close to uni and was thinking of walking home that evening but if they came and showed me their parking ticket I might consider driving home.
I'd get one or two at the start of semester and then it would be a pretty rare occurrence after that for the rest of the year.
Only two students ever showed me their tickets, the others waiting until I left. I even drove off one day and then walked back to see what might happen, and sure enough the student came out of the bushes and drove off.
