Partial Foods is Stain'd-by-the-Sea's only supermarket. In When Did You See Her Last?, Lemony Snicket was involved with the theft of honeydew melons from this store. The owner and worker at Partial Foods, Polly Partial, soon found him and reported him to the Officers Mitchum, the only policemen in the town. Snicket just got away with his crime with the help of Cleo Knight's fictional Dilemma car.

Partial Foods was mentioned again in the same series in the book Shouldn't You Be In School? when the schoolchildren of Stain'd-By-The-Sea were forced to steal all the honeydew melons for Hangfire by the villainous Sharon Haines. Lemony Snicket was watching this event from a nearby trashcan where Ornette Lost spotted him and they sneaked in a quick conversation.
