Describe Booker's experience on a train ride where he dines in the white section?

When on a train between Dallas and Houston, there were whites at every station who came and thanked him for the work he was doing. On another trip from Augusta to Atlanta, two ladies from Boston insisted he sit and eat with them in their section. When he finally extricated himself from the situation (for segregation laws required him to sit elsewhere), he found that the southern white men, rather than chastising him for being in the wrong section of the train, instead expressed their gratitude for what he was trying to do for the south.
