There is a right & wrong way to fill the toilet roll holders & the right way is away from the wall.
When someone puts it in so that the paper is closest to the wall several things can go wrong:
1) The wall gets grabbed & wallpaper gets fingernail indents.
2) The paper does not rip off from the holder properly, esp if it has a serated edge closest to the user.
3) Not having full control of the removal procedure, 2 ply+ often gets easily seperated
4) I get irritated.
When its in a holder that uses the serated edge, they are designed to have the roll end closest to that edge so that it creates a sharp angle & hence seperates the sheets when it is pulled off.
Not having it so is especially annoying when the roll is the large commercial ones that most public/factories etc use as the roll end then dissapears somewhere into the holder & because an idiot fitted it to the wall at the same height as a normal holder, you have to stoop very low in order to get your hand up there & retrieve it, thus giving you a bad back.
As you can see, this subject has been discussed with some people before...lol
