Again, Refilwe (much changed from the younger girl who was prejudiced against other immigrant Africans) is bothered by how terribly African travelers are being treated at Heathrow. This signifies a colossal shift in her attitude and outlook on the world. It also emphasizes the white colonial prejudice at play in England. Furthermore, it's noteworthy that Refilwe thinks of Britain as “our white civilization.” There’s some heavy irony at work here, since Refilwe is Black and likely doesn’t
actually think of civilization as “white,” but she understands how much power white people—and, historically, white
colonizers—exercise over the rest of the world.
