There are a lot of anglophones who have become francophiles because they love the language. They will find opportunities to shop in French, speak in French and relax in French. In any event, we are part of a reality. It's a fight every day in minority situations.
I always told my children that they had to ask people for things in French, that they had to shop in French. I always told them as well that they should not be rude if the person responded in English, because that was how we were going to work together. We still tell our children that they must speak to people in French first, be it in a boutique, a shop, a major chain store or a supermarket because you never know if the person in front of you is a francophone or a francophile. It is also an opportunity to speak French, regardless of the context. It's not easy.
