Answer:
(She yells out again) And I don’t want any back talk, you hear?
Explanation:
Kate's viewpoint that helps the audience understand that Eugene is disrespectful to her is seen in the above line:<em> (She yells out again) And I don’t want any back talk, you hear?</em>
From the interaction/dialogue between Kate, Blanche and Eugene, we discover that Eugene wasn't happy when he was told to put out the water glasses.
Blanche preferred to do it herself but Kate replied, <em>"Why? Is his arm broken? (She yells out again) And I don't want any back talk, you hear?"</em>
Then Eugene, <em>(Slams the ball into his glove angrily. Then he cups his hands, making a megaphone out of it and announces to the grandstands)</em>
Kate's statement that she doesn't want back talk actually reveal that Eugene is disrespectful; also, Eugene's angry disposition reveals that too.
