It's often cleaner than one in the cool, hip, vegan-only, fifty-craft-micro-beers-on-tap establishment I occasionally eat at.

In what country? I can't remember the last time I saw such a thing, so I think it's at least been multiple decades. If I did, I would, you know, probably not even attempt to use the restroom.

Arco and Valero in California are two chains that are effectively cash only (they take debit cards but charge a fee that's high when pricing it into the cost off gas). I no longer live in the US, but still visit family every year and I've seen those on every visit.

Oh. But those are big chains, so I probably would expect the bathroom to be decent.

I think these places are franchises so cleanliness and maintenance depends on the owner.
