In 'Black Like Me," what are the differences between the white and "colored" waiting rooms?
The two waiting rooms were set up to separate the African-Americans from the Caucasians. During this time of racial division, some whites considered themselves to be superior to African-Americans; African-Americans were, unfortunately and unfairly, considered by many to be "second-class" citizens, if that. Some Caucasians did not want to be in the presence of African-Americans and felt that it was beneath them to have to sit in their presence. It may have also been done to spite or humiliate (or both) African-Americans, as well.
