Here's the most relevant segment of the previous link for those without the patience to read the whole thing:

'No,' he said, 'look, it's very, very simple...all I want...is a cup of tea. You are going to make one for me. Keep quiet and listen.'
    And he sat. He told the Nutri-Matic about India, he told it about China, he told it about Ceylon. He told it about broad leaves drying in the sun. He told it about silver teapots. He told it about summer afternoons on the lawn. He told it about putting in the milk before the tea so it wouldn't get scalded. He even told it (briefly) about the history of the East India Company.
    'So that's it, is it?' said the Nutri-Matic when he had finished.
    'Yes,' said Arthur, 'that is what I want.'
    'You want the taste of dried leaves boiled in water?'
    'Er, yes. With milk.'
    'Squirted out of a cow?'
    'Well, in a manner of speaking I suppose...'
    'I'm going to need some help with this one,' said the machine tersely. All the cheerful burbling had dropped out of its voice and it now meant business.
    'Well, anything I can do,' said Arthur.
    'You've done quite enough,' the Nutri-Matic informed him.
    It summoned up the ship's computer.
    'Hi there!' said the ship's computer.
    The Nutri-Matic explained about tea to the ship's computer. The computer boggled, linked logic circuits with the Nutri-Matic and together they lapsed into a grim silence.
