American here. I don’t really go anywhere anymore, but ducking into a McDonalds, Home Depot, or any major chain has always been an easy bathroom option. I don’t think this has changed, unless drastic changes have happened in some major cities. I’m not in those cities.

The only change I've noticed more recently is more places that you described (especially fast food) has started to add door codes. Easy enough to ask an employee for the code though.
