To actually answer your question, even in the small town I live in the the middle of the US, cash is getting a little strange. Most people don't bother to carry cash, and are confused when places don't at least take credit cards. I sizable portion of places will do tap for a debit card and thus NG, but cash only is pretty rare, and I'd personally only expect that in a small, small town gas station or some sort, where they just have never bothered, and probably don't have good internet options anyway.
