Yes, that's right!
Not to generalize, but certain nationalities seem actually grateful for correction, non-linguistic speakers as they may be, f. ex. Hispanic speakers, Italian and most Latins (with notable exception of the French

) know they have trouble with English and appreciate the assistance. Poles, Germans, Scandinavians, Icelanders, also Turks and Hungarians, appear positively insensed if their English is corrected, even in the kindest, most undidactic manner!
The latter, much as a beautiful starlet who has been told she's gorgeous and without a blemish on her face, often give the impression (to me, at any rate) that they believe they speak en masse excellent English, from whom the rest of us can only benefit.
While it may be true that English-language instruction is superior in certain countries, this doesn't necessarily mean that the English-language learning in those countries is anywhere in synch. Why, for instance, is it "cool" for Germans or Dutch to misuse idioms, but "uncool" if Americans speak German or Dutch less than perfectly??
My discontent here lies simply in the double standard.
