Reminds me of going to Scotland and asking directions...
I did get a long convoluted reply though not aggressive . ***?
So I asked "Do you not speak English" and moved on.
We were checking into a motel in the SW of the USA and after the young woman on reception seemed not to understand us the other receptionist asked her what the problem was, 'I think they don't speak English'. We explained to her that the problem seemed to be that we did speak English.
