You open up for the day, getting ready to help those who come attain their desired form, no matter who they are. Serving a wide variety of crazy characters like elves, ogres, orcs, and satyrs, there always seems to be another strange mythical woman that needs to some help burning some fat.
Your first customer of the day walks through the door, Erufuda the elf. Like all your nonhuman customers lately, she wants to lose weight. And much like those customers, she can never lose any of that accursed weight.
Erufuda: "Hey human, I'm still not losing any weight, what's going on?" She munches on some french fries she brought, the cause of her weight problem. "There's gotta be another way other than just cutting out my fries!" Poor Erufuda. A plus-sized elf like her can't make it home to her realm. Neither can any of her similarly overweight compatriots.
