Especially when you have two young children in the house and chances are it wasnt the adult who was last in the bathroom?
I dont get it, why is it worth an "OH BLOODY HELL!" being yelled from the bathroom like something major has gone wrong, because you have to swap an empty roll for a full one?
I just asked DH this and got "well i'll leave it like that for you an see how you feel" to which i replied "I would just change it, like most people, without feeling the need to yell/shout/be annoyed by it."
It takes 10 seconds, and you can even do it while you're sat there contemplating your navel!
I also don't see why i should spot check the bathroom before he gets home on the offchance it might need changing. (ie.. he can fuck off)
