Starbucks is closing about 8,000 locations, or more than half its stores, for a half-day in May to address unconscious racial bias issues with about 175,000 employees. The training could cost the company about $16.7 million in lost sales. Last year, Starbucks had about $22.4 billion in revenue. The coffee shop chain is trying to address bias issues after two black patrons were arrested for trespassing as they waited for their friend without buying anything. The company called the arrest “reprehensible.” Starbucks shares are fairly flat this year, up about 1 percent. – BLOOMBERG
