Let's assume you will be a marketing person for a big US company. They want to sell products internationally, and they send you first to Munich, Germany, to meet the potential customer.
After your first day of meeting, they want to dine and wine you, and plan to take you also to the Opera, where the Carmina Burana are playing.
How are you going to impress them with your cultural-historical-literary understanding, which then will convince them that you are the right person to strike the deal?
