Jambon d'Ardenne (1977)

During the height of the tourist season, the rivalry between the manager of a slightly fancy restaurant and the proprietor of a nearby fast-food stand becomes quite heated, and shots are fired. In this comedy, the restaurant is run with an iron hand by its "patronne," and the help eventually have had enough. If that weren't sufficient trouble, the children of the owners of both establishments are romantically entangled, further infuriating the passions of the feuding food fanatics.

Unfortunately the movie Jambon d'Ardenne is not yet available on Disney Plus.
