The only time, I MEAN ONLY TIME, I have trouble with folks that do not speak English well are the ones that get MORE non-English speaking if it suits them . Living in Texas, we get this all the time when someone from the south of us finds it suitable to them at the time.

Case in point. I was once in an auto accident (very minor) and the guy involved with me acted like he couldn't speak a lick of English. Once we got to court and the guy was put on the stand and by the time my attorney got done with him, his non-English skills got better and better as the trial went along. In the end, the judge found in my favor citing the guy for lying about his skills at speaking in our language.
