Caught shoplifting

*author's note* this is an concept I've been tinkering with for a bit, but im not confident i can do it justice so i figured I'd open my idea up to the talented writers on this site, while also adding my own chapters when i get a chance. Thanks to any and all future contributors.

As you was walking through the mall you noticed a new shop had opened up near the food court. "B's magical sundries" according to the sign above the door seemed to be a junk shop full of various knick-nacks and other random items. As you walk through the store you notice one common factor, every single item is priced WAY out of your budget. The tags for each item claiming some far fetched magical power attributed to the item, most of which sound either too good to be true or like complete bull shit. Feeling annoyed by the exorbitant price tags on what looks like average junk you pocket something before making your way to the door. As your had touches the door handle you feel your body freeze, "Oh my whats this? My first shoplifter, how delightful." The clerk you says as they aproach you. "Tell you what my dashing rouge, since you are my first shoplifter i'll give you a choice, I either call mall security and have you arrested, or i can give you that item you were so **** to have, but with a twist." Not wanting the to get banned from the mall or worse you decide to take the strange shopkeep up on their deal.
