Dear Sirs….
Dear Sirs:
Some day you will move me almost to the verge of irritation by your chuckle-headed, goddamned fashion of shutting your goddamned gas off without giving any notice to your goddamned parishioners. Several times you have come within an ace of smothering half of this household in their beds and blowing up the other half by this idiotic, not to say criminal, custom of yours. And it has happended again today.
Haven’t you a telephone?
Ys
Samuel L. Clemens (a.k.a. Mark Twain)
A letter to the gas company; February 12, 1891
