Amatha Kooper is the younger sister to Lary Kooper and is the Ultimate Waitress. Sweet, cheerful, energetic, and non-judgmental, she has the patience of a saint. She also tends to be a bit bossy but nevertheless encouraging. Amatha usually bugs Lary to do silly things with her but he calmly refuses, though there are times where he puts himself aside to spend time with others and his sister. Amatha will also go all over the top depending on the circumstances.
