idk man, I get it's nice if things are clear for you, but it's misplaced IMO to have this level of entitlement over people speaking their mother tongue in their own country

I hope you get to learn Portuguese well enough that my fellow country folks never force themselves to speak any other language, in case you happen to visit us, if not, oh well.

I am fluent in several European languages and dialects, human languages is second nature alongside learning programming languages.

As for entitlement, the expectations on international trains crossing borders aren't the same as local trains, which I left out from the comment, it was an ICE after crew change.

It seems to me long-distance transportation services should make the most important announcements in the second language most likely to be understood by international travelers. In Europe, that usually means English.
