I had a ticket guide (proper folder and everything) and fare charts when I worked at Arriva. Didn't have these at GNE. As a former driver there are far too many tickets (and prices) to remember exactly what each one covers (and then when they rename things, change zones or introduce new ones). God knows how passengers are supposed to get their heads around it. When it came to stuff like transfer tickets I was given a black and white map which was as much use as a chocolate tea pot.
