Shawarma ink

So we were sitting around and trying to come up with a campaign for some product which isn't so important in the current scheme of things. What is important is the little discussion we got into about advertising. My partner said we're not into creating shawarmas. We're artists trying to come up with something creative, and that depended on being in the right mood and in the right space. I begged to differ. I said we're commercial artists trying to come up with one shawarma after another and making sure each shawarma is above average. Incidentally, a shawarma is a kind of pita wrap that's easy to make and quite delicious. So you tell me, is advertising about coming up with shawarmas or pieces of fine art?
