that each method makes it easier to tear the toilet paper on a perforated sheet boundary. In various surveys, around 70% of people prefer the over position. In a survey of 1,000 Americans, Cottonelle found that "overs" are more likely than "unders" to notice a roll's direction (74 percent), to be annoyed when the direction is incorrect (24 percent), and to have flipped the direction at a friend's home (27 percent). According to W. C. Privy's Original Bathroom Companion, Number 2, "By more than 4 to 1, older folks prefer to have their toilet paper dispense over the front." The same claim is made by James Buckley's The Bathroom Companion for people older than 50. Toilet paper orientation is sometimes mentioned as a hurdle for married couples. The issue may also arise in businesses and public places. At the Amundsen–Scott Research Station at the South Pole, complaints have been raised over which way to install toilet paper. It is unclear if one orientation is more economical than the other. The Centralian Advocate attributes a claim to Planet Green that over saves on paper usage. Various toilet paper dispensers are available which avoid the question of over or under orientation; for example, single sheet dispensers, jumbo roll dispensers in which the toilet roll is perpendicular to the wall, and twin roll dispensers. Swivelling toilet paper dispensers have been developed which allow the paper to be unrolled in either direction.
