what makes grant feel so uncomfortable in mr.henris house?

Grant, Miss Emma, and Tante Lou all go to visit Henri Pichot, a wealthy plantation owner who is married to the sheriff’s sister. Miss Emma and Tante Lou both worked as cooks for Henri’s family when they were younger, and they ask him to use his influence with the sheriff so that Grant can visit Jefferson, who is only allowed visits from his priest and his family. Grant objects to visiting through the back kitchen door like they are slaves or servants.
