I pretended to know wine at a business dinner and now I'm the company's wine guy

I said hmm, earthy. Once. ONCE. Now the MD passes me the list at every dinner. I pick the second cheapest and say something about structure. Last month a client asked what region I preferred and I said the south. The south of WHERE, Kunle. He nodded. I think he's also pretending. We're all pretending. Pass the list.
