Answer:
She resents the cameramen's presence because it makes her feel inferior.
Explanation:
<u>Grandmother - called Granny by the author in the story - is angry with the presence of the white cameraman that is trying to exploit the life and habits that they have as a family and make a story about poor people and food stamps. </u>
In that kind of relationship, <u>the cameraman is posing as a wealthier person, knows better, observes the poorness as something exotic, interesting and worthy of the "story" for the state. </u>
That is why Granny feels inferior. She sees the fact that the cameraman is trying to make a story about poorness and lesser living from their life, and she doesn't like to be observed by someone who finds publicizes her and sees her alien in a pejorative way.
