Yes. I was once asked to translate by an English only speaker, who could not understand the broken English of another Dane. The Danish guy got very angry with me for not thinking that he spoke perfect English and taking the job. (PS: all Danes think their English is just fine. It is particularly noticeable when artists or high level politicians speak English on public occasions (and make ridiculous mistakes) ) There is even a song about it:
That has never happened to me. However, I have gotten close to angry at numerous students over the years who had trouble with the English language. And I'm NOT talking about the girl from Vietnam or the brother and sister from Lagos or the two Haitian refugees etc. They spoke great English.
