But I've spent months of my life telling various US based employers all the ways their assumptions about languages were wrong, and it was often a weird level of blindness where they'd be aware of some exceptions but fail to realise the same pattern repeats lots of places.
You'd see companies with separate Spanish versions of their US services still struggle to deal with the existence of Switzerland, for example.
If you really want to blow their minds, show them websites of the Government of Spain, which have separate versions in Basque, Catalan (+ Valencian) and Galician as well as in Spanish.
