This is not true. The American's didn't come up with it, the Americans don't drink the most of it per-capita[*], and the Americans don't drink that much of it.
It would be fair to say "decaf is a rich country thing", though.
[*] although in absolute terms, they import more of it than any other single country, but there's a lot of them
It seems very common for people to think that if there’s something they’ve heard about from American pop culture (or the internet), but isn’t popular in the few countries they’re familiar with, it must be uniquely American.
Yes! I wasn't sure how to express that without sounding like a dick, but I remember a comment a few weeks ago where someone was suggesting Amex was unheard of in Europe, where what they really meant was it isn't in Ireland, where they were.
I meant American in the sense that is is consumed so much by Americans. And yes it is also related to economy and many places you will find barely any shop that will offer that. That is not the case in the US.
edit: I feel like I was ignorant about this and my assumption was wrong and not based on facts. sorry about that.
