If there were communication difficulties, rather than acknowledging it as a two way thing, the blame was put entirely on the tourists which I always thought was a little unfair. Ad astra per aspera
To avoid resentment when travelling in Europe, I'd have to learn upwards of five languages.
There's a case for French and German, perhaps for Spanish, but if you try to include all possible languages in the school timetable they could eat it alive.
A more interesting plan might be to start a Euro-literacy project for the UK, with subsidised holidays and visits, evening classes, and family exchanges.
This assumes that the government would be pro-EU, which clearly it isn't. But I think for many adults school - especially not school in the UK - is not the best way to teach anyone about being an EU citizen.
No, the resentment doesn't come from not speaking the host language but from expecting the hosts to speak yours.
