I have rarely had individuals who want to get paid in cash (off the books). But although some businesses like my furnace company are slowly switching over to having portable terminals, in my experience, checks are still the default around where I live in the US for service people and the like. (And, as I wrote elsewhere, even things like local tax payments can have outsourced third-party websites which charge a fee so it can be materially cheaper to pay by check.)
I've never been told cash, but if I was, I would be happy to pay in cash.
