its that Just in time supply system,  they've got someone from 'Buisness' who reckons they can run things cheaper by keeping no stock of spares, because you cant go anywhere else for supply, so when something goes wrong they have to ring their suppliers, who have a similar idiot in charge who also has no stock of spares, but it's all cheap.

Any idiot can face a crisis - it's day to day living that wears you out.
