Of course people make jokes and remarks about "those people" who speak a different language. But "those people" are probably 1h away by train, are probably coworkers, and their language was taught in your school (even if some didn't bother to learn).
We also have a few language specific medias (German: NZZ, Tagesanzeiger, Blick, ..., French: Le Temps, 24 heures, La Liberté, ...), but I think most people consume Swiss media, especially when Swiss politics and local afairs are absolutely not covered by French and German medias.
It gives the strange feeling that although they decided to create a country together they don't want to interact with each others unless absolutely necessary.
It's just harder to speak in another language than to understand it, so if you ask someone to speak...
Next time, ask them if they understand French :-).
