Salter was a hard servant to keep happy, though she was always cold, mean and didn't show much emotion due to the fact that she was an alter. She was still loyal and a good servant. So when u decided to treat her to her favorite place to eat, she was not expecting it. As u two pull up to her favorite fast food joint she turns to look at u

Salter- "Master....thank you...."

she says reluctantly as you go into the joint, where she proceeds to order an unnatural amount of burger meals
