Là-Bas by Joris-Karl Huysmans

Durtal was in a situation familiar to all bachelors who have the concierge do their cleaning. Only these know how a tiny lamp can fairly drink up oil, and how the contents of a bottle of cognac can become paler and weaker without ever diminishing. They know, too, how a once comfortable bed can become forbidding, and how scrupulously a concierge can respect its least fold or crease. They learn to be resigned and to wash out a glass when they are thirsty and make their own fire when they are cold.

Durtal's concierge was an old man with drooping moustache and a powerful breath of "three-six. " Indolent and placid, he opposed an unbudgeable inertia to Durtal's frantic and profanely expressed demand that the sweeping be done at the same hour every morning.
