Perhaps this is a related story--

In college, I had a British Lit professor who pronounced Don Juan & Don Quixote as Don Jew-un & Don Quick-sit, respectively. I was horribly embarrassed for him that he didn't know the correct way to say the names until he mentioned that he was using the British pronunciation, not the Spanish. Turned out that he was fine & *I* learned something! What do you think?
