I apologise for going OT but curiosity must be satisfied.
So, the trap at work has a normal loo roll holder (as opposed to one of those corporate jobs where you need a key). On a shelf in the trap is a bumper pack of Tesco's cheapest loo rolls.
What I've noticed is that, from time to time, an unattached loo roll appears parked on top of the loo roll holder, which continues to hold a roll with plenty of sheets. I can understand when the loo roll is parked on an empty cardboard tube - obviously mummy isn't on hand to change the loo roll for diddums, but why do some men (a man?) find it necessary to start a new roll when there's a perfectly serviceable, unfinished roll on the go?
There must be a logical explanation - I work with software engineers, and we're not known for being illogical, Captain (sorry, saw the Star Trek film last night!)
