The arrests of Nelson and Robinson were captured on video by another customer. As the video went viral on social media, it stoked widespread outrage and days of protests, and caused major embarrassment for Seattle-based Starbucks, which has long marketed itself as having a socially enlightened corporate culture. CEO Kevin Johnson, who then visited Philadelphia on damage control, called the arrests "reprehensible" and announced that the chain would close all of its U.S. stores on the afternoon of May 29 for its 175,000 employees to undergo racial-bias training. Some activists said the training would not be enough and threatened boycotts.
