Bubakar insults Winston, despite the fact that Jende is visiting Bubakar on Winston’s recommendation, because he’s probably intimidated by Winston’s more prestigious and lucrative career. Bubakar thinks that the story about warring social groups will work because of how little he thinks the immigration authorities know about Africa and their likely assumption that tribal conflicts occur all the time. To Winston, the story sounds implausible because he understands Cameroon’s sociocultural context and knows that such a thing wouldn’t happen in practice.
