The very first time I was on a car in Atlanta I saw the conductor - all conductors are white - ask a Negro woman to get up and take a seat farther back in order to make a place for a white man. I have also seen white men requested to leave the Negro section of the car.
I do think that at one time being an actress was the equivalent almost of being a prostitute. It garnered roughly the same respect. That's changed a lot thank goodness.
