Ours was neither! The cat loved to eat paper. So the roll lived in a cannister on the back of the toilet.

I have been known to remove and turn the roll, to get it in the correct dispensing position, in other people's houses. I don't care.

My OCD will not allow me to leave it rolling backwards. It's just not happening.

Yeah, well. My ex beat the right side into my head. For the first year after divorce, i purposefully did the left side. There is a reason for why...... the left side won't stop unrolling as quickly sometimes.
