Starbucks is taking the racial-profiling incident that happened in one of its stores in Philadelphia very seriously. In response to the incident, in which two black men were asked to leave the store for no actual reason, Starbucks has announced that it will close more than 8,000 company-owned US stores for a day in May to conduct racial-bias training. The coffee giant will instruct almost 175,000 workers in its stores and corporate offices, using a training program that will also become part of the on-boarding process for new employees.
