"The Bluest Eye" close reading

I decided to look at both the context and the language used in a certain passage. On pages 48 and 49 Morrison is talking about when Pecola is going to the store to buy some candy. Morrison talks about the reaction the man in the store has to her, and how he feels. One thing I noticed was that when Pecola was trying to tell him which candy she wanted he responded by saying "Christ. Kantcha talk?". Even if you consider the time period for this piece it is quite interesting to note, that even he, can't talk all that well. He seems to stumble in front of a young girl, its as though he is scared of her. Another part I found interesting was when she went to pay him for the candies. He was reluctant to touch her hand to take the pennies, and why? All because she is black. I also think there is some idea of superior/inferior throughout this text. The stereotypes also come back into play...
Its also sad to read that she knows his distaste for her is her "blackness". Even at such a young age she knows, or at least seems to know, that she is considered to be the lesser between the two. Is
