Anglo Saxons dislike use of other languages around them.
Yanks in particular are "anti-Spanish"... Espaņol hurts their eardrums.

Circa 2000, Buenos Aires, I met an old PanAm buddy, who was with United.
They were at the Sheraton/Retiro. I invited him (and F/O) for dinner at home.
My wife, native of Buenos Aires, spoke no English. Was Spanish together.
Great dinner, bife de lomo, best wines, etc...

I translated all conversations. A bit tiring, but I was accustomed to it.
Then wife being present.... these guys criticized us.
"Why dont you teach her to f*** speak English"...?
My wife, despite her limited English, understood what they said.
She suddenly became quite proficient... "Zis is our home"...
I never invited USA friends for dinner at home again.
