These are garments, Mr. Cratchit. Garments were invented by the human race as a protection against the cold. Once purchased, they may be used indefinitely for the purpose for which they are intended. Coal burns. Coal is momentary and coal is costly. There will be no more coal burned in this office today, is that quite clear, Mr. Cratchit?
Now please get back to work before I am forced to conclude that your services here are no longer required.
