<Snipped quote by Dagger>

Take it from someone who learned English very late in life, people do not randomly inject words from their home language into English. Hollywood often does this with say a French guy saying "bonjour" to great or a Spaniard exclaiming with "puta" but this really doesn't happen that much, its a cheap way for movie makers to emphasize the foreignness of a character without doing something meaningful with them. There are exceptions, i.e. hotel staff because its expected of them to endear them to clients, but its something to keep in mind during judgement.

That’s an interesting point, and I definitely don’t doubt it. However I also have a couple Latinx friends who do use “Spanglish” in their daily life, so I wonder if there’s some variation across people from different cultures? Living in the southwestern region of America, we have a lot of people from Mexico in my county, and it seems to vary even person to person whether they weave Spanish into their speech or not.
