What a insightful talk about Sommeliers and what it takes to be a professional wine waiter; It is not easy with rigid rules. I don’t drink so I’m not familiar with this sub speciality, but it is not different when compared to a customer asking for a well-done steak ?; such a request infuriates chefs. Fine restaurants are business establishments that seek to please its customers so it wasn’t surprising to know that Sommeliers keep track of their customers spending habits.
