As was mentioned in a thread a couple of weeks ago, we have experts in all sorts of things on this forum. For once, I can offer my expertise in this matter. As a cleaning supervisor (And I`m proud of it
) who holds nvq`s in cleaning building interiors (I kid you not) the correct way is for the roll to be facing away from the wall. In public loo`s where the large holders are on the cubicle walls, the holder should be on the left with the dangling loo roll nearest to the person sitting on the loo and not the furthest away. Believe it or not, people where I work do complain when the roll is the wrong way round.
