Language is fake and there are no rules. So long as it doesn't actively impede the ability for people to be understood, there is no need to "correct" language. (Even then, maybe you could just ask for clarification instead of being a self righteous prick about it) You sound like that teacher who would condescendingly ask "I don't know can you use the restroom???" when you would ask "can I use the bathroom?" instead of "may I use the restroom?" Nobody likes that teacher. And, because I'm a leftist on the internet, I need to point out that refusing to address someone until they "spoke right" is some Jim Crow era shit that can and has been used to enforce bigotry of all sorts.
