Accents and countryisms are not to be commented on. It is never a good idea to make someone self concious of the way they talk. It’s a dick move to say something like ‘Why are you calling me hon? I don’t even know you?!” That not only makes you seem like a prick to everyone who hears, but it puts the person you’re asking in an uncomfortable situation by having them explain that they were raised around that kind of thing. And that they were just being neighborly.
Believe me having to explain it is really upsetting for some reason. It’s like having someone demand that you tell them why your hair is blonde when brunette is so much prettier.
