Some still do.

There's a restaurant five minutes from here that doesn't take checks or credit cards.

NONE of the breakfast and lunch cafes in the local office buildings takes checks or credit cards.

Farther up the same road, there's a grocery store which only started accepting credit cards in the last month or so.

I could be mistaken, but I don't think the Ohio Turnpike takes checks or credit cards.

The sole washer and dryer in my apartment building requires quarters. I've never tried to buy a roll of quarters at the local grocery store with a check or credit card.

The RTA buses here require cash.

It's still necessary to have cash.
