"(But the coffee cup is useless without coffee!)"

Here, I disagree (or agree with you, depending on whether your italics indicate e-sarcasm).

You could fill it with water or tea or make your own coffee or even sell it to somebody else at nearly full value! (I'm sure the restaurant support would be happy to welcome a new customer back to the fountain of coffee).

You get my analogy.
