To graduate highschool in france you need to have taken and passed at least 6 years of one secondary language and 4 of a third, most take English for one of those languages and culturally the place most known for the snobbish behaviour historically is Paris, from supressing other languages in France such as Catalan, Basque, Occitan, Breton, Normand, or Frankish, which have begun to disappear completely over the last 200-300 years in favor of the modern French of Paris. Paris culture has a long history of thinking it is the best culture in France and above others in Europe, the term langue franc or lingua franca comes from Parisian French being the primary international language, calling everything from Haitian, Occitan, Normand, and other similar languages as a Patoi a french, a term meaning a derivative of the French language when. Occitan and Frankish are much older languages than French and in the case of Frankish is a language that evolved into French.

Now with that bit of history and culture out of the way, which shows the suppression of other internal cultures if you want to call it that and erasure of their languages from public use and the elevation of French, which came with the centralization of political and economic power in France in Paris, it lead to a culture within Paris that started with the capital of the monarchy permanently setting up their bureaucratic institutions there then the revolutions starting there, leading to a major cultural centralization there and a sense of superiority compared to the rest of france which endures to this day, be it someone from Lille, Marseille, Toulouse, Dinon, Lyon, or elsewhere the Parisian culture sees those major cities as secondary in cultural additions to prance and Paris as the jewel in the crown. This sort of cultural snobbery led to other regions of France, while maybe less able to speak English in the past than Paris, having a less snobbish attitude than Paris, as well as a more friendly attitude to foreigners as a whole (look up the 1961 Paris Massacre for more context)
