I'm having the same problem learning German in Berlin - everyone speaks English here and the slightest mispronunciation or "vie bitte?" and they switch to English. Which is appreciated - I'm a foreigner in their country and they're being incredibly hospitable to speak my language - but it makes practising German very difficult.

Also, a Swedish distant relative of mine told me (decades ago) "We Swedes prefer to talk to foreigners in their own language, and keep Swedish as a private language for ourselves". I've never heard that said by anyone else, but it has always stuck with me as a cool idea, and the antithesis of the English ;)
