You’d be surprised at how many places there where this is true. Obviously with respect to construction crews and landscaping crews and kitchen crews, etc., there’s no room for non-Spanish speakers. But you might be more surprised, I used to work as a legal aid attorney, and all support staff was required to know Spanish, and even several of the positions that required law degrees.
I go to a super market in the United States whose prices and item names on shelves are in Spanish and English (ditto for their mailed ad sheets)and who sometimes make in-store PA announcements in Spanish. Outside the store is a big sign that reads; Carneceria (Meat Market) but without the English equivalent. We are becoming bi-lingual, perhaps soon to be poly-lingual if the progressives hold sway. And English is still not the official language of the the United States.
