You mean “rich” and well to do Nigerians right?Boule ADOS folks and Nigerians tend to do the same kind of 'sizing up' when it comes to other black folks. Asking your family name, where people went to school, what church they go to, etc etc. Lotta folks never seen that look of disgust an older Boule person gives someone that doesn't pass their test lol. Luckily I have never been victim but its crazy. When you are first get college student/middle class you still have that 'damn aint we all black', but them folks are real protective of their circles. I'm not going to say whats right or wrong, but their reasoning is to protect their positions on the food chain.
I don’t like the conflation of upper class blacks to “normal” everyday Nigerians. As if a upper class blacks and everyday Nigerian are equal on the socioeconomic landscape. May not be your intention but appears that way.
