SEOUL, South Korea -- Starbucks has more than 2,000 stores across South Korea, including one that overlooks a North Korean village, one in a century-old traditional street market and one that sits on the 99th floor of a glass skyscraper. In a first, they all closed early on Monday. But the 3 p.m. closure did not mean extra time off for its 24,000 or so baristas, supervisors and corporate employees. Instead, they all had to do training on historical awareness and cultural sensitivity.
