Titanic’s plot revolves around members of different social classes falling for each other. Rose and her mother, Ruth DeWitt Bukater (played by actress Frances Fisher), belong to a privileged stratum, so they are supposed to know the etiquette protocols very well. In fact, on several occasions, Mrs. Ruth reminds others to comply with them. That’s why it seems contradictory that in several parts of the film, she wears gloves to snack when the rules of etiquette forbid this: she should take them off when entering any room where food is offered.
