My comment to my girlfriend the other day was, "you can always tell when someone spends too much time in the bathroom if they actually have a toilet paper technique".
I'm a fold, but it requires a series of different sizes. When im in a public bathroom, I'll set up 3-4 ready to go, since the rolls are inevitably too low to the ground as it is, and nothing worse then the pull, ... rip .. pull ... rip .. curse ... pull ... rip of the cheap public toilet brands.
