I can take this worthless piece of paper, go to the supermarket, give it to a complete stranger whom I've never met before, and get, in exchange, real bananas which I can actually eat.
Mogu uzeti ovaj bezvrijedni komad papira, otići u supermarket, dati ga potpunom neznancu kojeg nikad ranije nisam sreo, i dobiti, u zamjenu, prave banane koje zaista mogu pojesti.
