1) What, praytell, do y'all consider a "middle European" accent? There are a lot of countries, languages and dialects (hence accents) in the center of Europe.

2) Castillian Spanish accents are extremely rare in the United States. Y'all should watch on 'o them thar formerla one races to hear a true spanish (as opposed to hispanic)accent.

3) Which Mexican accent do you find offensive? There are several. I had several employees from Mexico, and I had one who spoke to me and translated the others for me. I could understand Miguel, but couldn't understand three of his compatriots (also from Mexico) as they had a different accent to their Spanish. I almost got into an altercation with them one day because of a misinterpretation, after which I relied on Miguel.
