As an Australian I can comment on this, theres this wonderful thing called “Context”
At McDonalds they refer to them as fries, but if you ask for a large chips, they know what you mean. If you go into a petrol station and ask where the crisps are, nobodies head explodes. If you go into a place that has ALL 3 (french fries, chips and crisps) and say “Can I get some chips” the person will ask for clarificaton.
British roots and American television has made OUR english quite flexible.
Pretty much.
it holds, but we might refer to “fries” as hot chips if there’s possibility of confusion
I would say the distinction between fries and chips is the thickness.
Macca’s has fries, KFC and a lot of other places have chips.
Do they have Red Rooster and Chicken Treat in the US?
I’ve never heard of either so my guess is no.
