Given the following sentence, is "indignantly" used correctly:
"I can't believe a filthy beggar like you would dare to even speak to us!" the lead girl in the trio indignantly shouted at him.
The definition of the word "indignant" states that it is "showing anger or annoyance at what is perceived as unfair treatment."
In this case, the person is definitely angry, but she is clearly looking down on the beggar. She also clearly thinks it's inappropriate that he's spoken to her, but it's not really "unfair" treatment. Is "indignant" properly used in this case?
