I’ll bite.

It might have been different a few decades ago, but in the UK these days fries are still fries. Nobody would ever ask for a Big Mac and chips. Chips are specifically much fatter ‘chipped’ potatoes. And potato chips are crisps.

So if we’re talking objectively… Fries are just the same US and UK. But US potato chips aren’t actually ‘chipped’, they’re very thinly sliced. And ‘crisps’ are indeed very crisp.

So I’d actually say the UK descriptions are more objectively correct.
