tell me a story about a slim girl from a poor family, who always wanted to be fat. she applied for a job as a waitress in a restaurant. she convinced the owner that she won't get any money from them, in exchange of a place to stay and the leftover food of their restaurant. since the restaurant's food quality was bad, there were many leftovers which she could eat. after some time and gaining a lot of weight, she became so large that she could no longer fit through doors. now, she could no longer use the wc or leave the restaurant.
