This story wasn't bad, but I didn't relate all that much to the protagonist. On the other hand, the descriptions of her cooking made me very hungry! the idea that the tradition of feeding ghosts disgusting things when they really prefer normal foods is a strange one. Why don't they just go to McDonalds and steal people's hamburgers?
The beginning was a fun hook with him describing the colors of the owner's face, but in retrospect it didn't fit the story well. At the beginning it was set up as though that would be the climax of the story, the final confrontation, and then it steps back in time to explain how that point was reached. But in the story, that moment was a very minor, barely mentioned, moment, so it didn't tie together very well.
