I read a sentence:
Air power is like poker. A second-best hand is like none at all — it will cost you dough and win you nothing.” — General George Kenney,Commander of Allied Air Forces in the Southwest Pacific, 1942-45.
In daily use, "dough" often refers to money. In this sentence, does it also mean "money"? Does "dough" always mean "money" in the expression "cost you dough"?
