fines are 30 quid a time. my mate left it there for a while and got 90 quids worth. every so often...everyday?! lol not joking, you gotta play it carefully, avoid the clampers. they warn you first, then they go clamp happy. but to be honest, unless you're going home every week, there is absolutely no need for one. buses go from uni every 6 minutes, and i can pretty much guarantee there will always be one there into town everytime u go to the bus stop. transport is amazing there.
