The Thirteenth Doctor, Graham O'Brien, Yasmin Khan and Ryan Sinclair sat inside, discussing Rosa Parks. However, moments after sitting down, people stopped talking and stared at them. A waitress came over and told them they will not be served, due to Ryan being black and Yasmin for being brown (or "Mexican", in her terms). She told them to get out. Due to their hatred racism, he group left in disgust. (TV: Rosa)
