You can't really think this way. You can't imagine how many people speak a non-grammatical English, even if they are native English people.
She's a teacher and probably spent years studying the correct English (grammar, spelling, etymology) and not the one that everybody speaks.
For example, you can hear a lot of people say "it don't matter" or "what you said?" which are okay but only as an everyday English, and some people won't even notice the mistake. But both are grammatically incorrect.
I think this problem is the same everywhere whatever the language.
