Somehow, 8 – 24 oz cups are an American thing. Getting what I consider to be “a cup of coffee” means 5 or so “cups of coffee” in most places. I think the generally-referred to “cup” here is a teacup (thanks to the British). To my big American self, the first few days were spent trying to break the language barrier enough to convince someone I really DID want what must seem like a bucket of coffee.
It’s these little cultural differences that fascinate me. How something as invisible as the size of a vessel is not standard around the world.
