Magic?

I offer money made of metals, paper, rag, dyes that must be mined, grown, reaped, designed, minted, printed in how many ways I know nothing about by how many people over how many months or years?

In exchange, I receive a paper cup (How is it made so well-shaped, rolled over on itself so neatly around the perfect circle of the brim?) filled with coffee, cream, chocolate, cinnamon, nutmeg, most of it cultivated by people whose language and ways are strange to me, thousands of miles from here, then processed (from beans and cows and bark...don't ask!) and gotten here, heated, chilled, brewed -- and I don't even remember how to make one lousy molecule!
