French speakers of Quebec use the informal second-person pronoun "tu" more often and in more contexts than speakers in France do. In certain contexts it may be perfectly appropriate to address a stranger or even the customer of a store using "tu", whereas the latter would be considered impolite in France. The split often runs across generations in Quebec: Persons between 40 and 60 years of age often feel that sales persons, or service personnel giving them a "tu" instead of a "vous" are uncouth or uncultivated. Persons 60 years of age and older will sometimes feel insulted if a stranger uses the "tu" to them. Government employees (such as policemen or bureaucrats with some contact with the public) as well as employees of large stores or large chains in Quebec are usually instructed to use "vous" with everybody, unless some kind of "camaraderie" is in play or they know the person well. Sometimes the split is also across social or educational lines. For instance, young academics are usually hesitant in using "tu" with slightly older colleagues who have just a few more years of seniority.
