A band does a gig at the 'Cornmarket'. Wouldn't the Corn Exchange allow its name to be used?
A student says he is studying 'Economics and politics'. I don't think anyone would say that. It would have been Economics or SPS.
A student refers to a college's site as a 'campus'. Would anyone have done that? Do they even now?
Of course, I could have mistaken these and they are in fact a carefully planted set of indications of an unreliable narrator/author or something. And, sure, they don't stop me enjoying the book, but they did bother me.
