See the difference between them? Chips isn't our word for fries. We have fries here too. If you go to Burger Hut, or Kentucky Fried Black People Food, they serve you with fries, because that what the are, fries. Go to a Fish and Chips shop, and they will serve you with thick cut, potato filled CHIPS.
