I was somewhat shocked to read this anecdote in the Times this morning:

<< The songwriter Stephin Merritt, the frontman of the band the Magnetic Fields, has trained his gaze on a quarry as seemingly picayune as toilet paper. “In other people’s bathrooms, I routinely reverse the direction of the TP roll,” he said. “Contrary to the advice columns, the paper should hang toward the user, so it doesn’t require fumbling and scratching with the fingernails. A mnemonic: hang out in the bathroom.” >>

Would you ever reverse the direction of someone else's toilet paper roll while using their restroom?
