As an American: vinegar on fries is good, and we agree with them, Ketchup (#1 fry sauce) is vinegar and tomatoes!
The ones I had done “properly” by a Brit I knew came out nice and crispy, then you put a little vinegar on them, not a ton, and it lightly seasons them without getting too damp. Can also help with the heat if they’re fresh
