I see a great potential for paper saving by not printing timetables, when the bus always comes late, or doesn't come at all
@piggo
A friend, many years ago (when I had a few) was once sent a gift card for a supermarket by her local bus company for making the suggestion that they change the timings of the buses on the timetable giving each journey time a few extra minutes leeway, since they were, up to that point, almost always late under their extant timetable.
@piggo I've seen the bus here arrive and leave *early* (usually from the other side of the road, causing me to miss it).

Not like trains, that are always, dependably, late :D
