What I find much more of an issue is people who can't or won't put the toilet roll on a spring type holder (like this
). They aren't hard to use and there is no need to leave the new toilet roll perched on top of the empty one.
The one I have in my flat is a pain to use. It's not like that one, it's just a bit of plastic that can be bent weirdly (with a lot of force). I just let the cleaning staff do it.
I'm usually over. I don't care much, in my last flat we didn't even have a toilet roll holder and here we have a toilet showerhead (in fact, I have only that at work because I can't be bothered to carry toilet paper around with me everywhere).
It's awesome. They should have them everywhere...
