Why does walter pour syrup on everything and why does atticus get angry at scout for noticing? Does walter get enough nourishment at home? Why or why not?

Scout was troubled by the fact that Walter spilled syrup all over her vegetables and meat, since she was brought up in a home that took table manners into consideration.

Walter's acts go against all that Scout was taught from an early age. It is gross and discourteous to spill the syrup all over your plate.
