. Well no, not really, but people do anyways. Tutorials are usually fine with most classes. Lecture's, well as long as the lecturer doesn't see. Most of the time I do anyways (whether its coffee or EasyWay).
I don't go to Starbucks around uni, so the only one I know of is at Capitol Square, which is further than Gloria Jeans, which is at Railway Square, Ultimo Road, Market City and Broadway.
