BTW my earlier mistake shows the danger of making assumptions. For example the users of the system may have had in mind a relationship where a theater is listed by all zip codes for which it's considered "close enough", implying a many-to-many. Or, it could be that a zip code is assigned a lat/long coordinate or bounding-box lat/long coordinates, as are all theaters, and the query is supposed to do some sort of spatial operation, implying no direct relationship at all between theaters and zip codes.
