Karyn's first thoughts treaded toward the vile and cruel. She wanted to turn Sarah into some clothes, or a dog. Perhaps into a Genie. Interestingly, Karyn rejected the last idea almost immediately, feeling that being a Genie wasn't much of a punishment at all.
Then Karyn remembered that, even as clothing or dog, Sarah was required two more wishes. She realized that her best chance at vengeance was to make Sarah desperate. Force her to use that third and final wish in an unbeliebably stupid way. Knowing Sarah, that wouldn't be too hard. So, she choose a more conservative interpretation.
"Your wish is granted, my Mistress." Karyn announced, "I have made it so your purse will alway be filled with enough cash to purchase whatever you so desire." She did not, of course, inform Sarah that one of the limitations of Genie Wishes was the First Law of Thermodynamics. Karyn could niether create nor destroy matter. Therefore, that Sarah's money must come from somewhere . . .
Sarah smiled broadly, "I believe it's time to shop then."
"As my Mistress so desires." Karyn curtsied to Sarah. Perhaps, one day, she would do the same for a Master she truly respected.
"Yes, as I desire. You are becoming a wonderful servant, Genie. Still, I must make you return to your lamp. I cannot have you slowing down my shopping spree." Karyn was once more broken down into dust and returned to her true Owner, the lamp.
Inside, Karyn eagerly awaited Sarah's next mistake.
