A spoiled rich girl

You take in your surroundings, it seems that you're in the aftermath of some kind of fancy party. Your box lies tossed-aside in a pile of discarded packaging and expensive gifts. You see a young woman sulking in a chair in the corner. Looking down at her lap, she hasn't noticed you yet, she is wearing a knee length yellow dress with white ribbons, the kind of dress that fetches a high price due to it's designer pedigree and expensive materials despite it's seemingly common appearance.

You step forward, and as your shadow moves into her peripheral vision, she looks up, an expression of fear quickly possessing her.

"Do not be alarmed, mortal for I am the genie of the box, and it is my duty to grant you three wishes." you say.

Still frightened, your would-be mistress responds with a scream and removes one of her shoes, chucking it towards your head. With a simple wave of your hand, you freeze the projectile footwear inches from your face and gently lower it to the floor.

"There's no need for any of that" you exclaim calmly, "now, once you calm down, we can discuss the matter of your wishes."

Eventually the girl's initial shock changes shade to a timid curiosity, her eyes scan your body, then stop wandering suddenly as she notices that you can clearly see her.

"So you're telling me that I can have whatever I want?" she finally asks

"if it is within my power, I shall do as you ask of me"

"Well, I guess my 19th birthday wasn't as lame as I thought it was. What's the point of even getting me anything, if I can already buy it whenever I want?"

"Perhaps, you should appreciate the fact that your friends wanted to do something nice for you."

"I guess, but..." she seems to think for a moment.

"yes?"

"Clearly, you don't understand, these people are hardly my friends, they mostly just like being around me because of my family's wealth."

"I am literally a genie, mistress, mortals don't typically simply enjoy my company without asking anything of me."

"Whatever." She brushes off your attempt at sympathy. "I get to make wishes right? I wish to have the party of a lifetime."

And so you receive your first wish from your new master. Honestly you aren't getting a good first impression of her, but you haven't really seen her do anything wrong besides acting entitled. There are a lot of ways you could spin this. She wants a party, so you could send her to a party anywhere in the world. You could also summon a party here, the wild sort of party that will leave her home a wreck to teach her a lesson.
