Twitter has ruthlessly mocked Starbucks campaign for the company's new anti-racism campaign in which baristas talk to customers about race issues while serving their coffee. One user tweeted, 'I don't have time to explain 400 years of oppression to you & still make my train', while another pointed out, 'y'all realize there are no coloured hands in the press photos right'. A third speculated, 'maybe Starbucks actually wanted to get people of all races & ethnicities to join hands and make fun'.
