It will because no "correction" is necessary. If the speaker's intent was understood by their audience then their usage was correct. If it was not understood, the audience will seek clarification and the intended meaning will emerge that way.

This sort of unsolicited "correction" of other people's language is unnecessary and basically never helpful outside of an explicit educational/language-learning context. The goal isn't to perfectly communicate according to a specific set of rules, and trying to ossify the descriptive "rules" in that way is just prescriptivism but slower. The goal is to understand and be understood, which will always be a context-dependent moving target.

There are always other factors being communicated besides the pure meaning. Shibboleths like this one can be class/education level indicators.

That's an interesting perspective, I see where you are coming from now. Thanks for elaborating.
