while we're on the subject of loo rolls I'll share a fond story...
My parents used to have a small campsite where a lot of regulars used to come back year after year, every now and again the loo's would get blocked as someone was using newspaper instead of the nice loo roll provided, this caused no end of problems, and one particular regular kinldy painted a sign asking people to use loo roll not newspaper, this continued, and near the end of the season again the loo's got blocked, only this time the person had used the front page of the paper, and it was I think the Chester Times.... this helped find the cause of the problem.... who was the nice little old man who painted the sign!! My parents never confronted him, I think they just mentioned the front page paper, and it stopped!
He continued to come and stay with his wife, and became my adopted grandparents!!
