You have to consider what is more awkward....
#1 Someone walks into the bathroom and sees the toilet paper roll hanging on the wall??
#2 Helping pick up someone who is screaming and just fell off the toilet because he put his back out trying to reach the toilet paper hanging behind him??
I would say number two is more awkward, but, since I have a bad back that would go out trying to reach behind and to the left like that, I rather picture myself being the one on the floor screaming.....
