Yeah, like the Philippines.

AC is common enough for everyone to have seen and felt AC. Especially at malls, busses or other public places. USA has more AC but that's not really going to wow anyone.

Even in the Philippines, there's plenty of hotels with AC if the locals want to spend extra money on a vacation. But more realistically, Filipinos will get large amounts of AC at movie theaters or malls. Even if its not something Filipinos can afford in their individual homes, its something that they'd have come across in their daily lives, and it wouldn't be something that they get "wow'd" by.

Fewer than 25% of homes in the Philippines have AC, and I promise you that the climate in the Philippines is much much worse than even USA. Far more humidity and heat. Europe has milder temperatures than USA so they don't need AC (but they have enough money / luxuries that they can afford AC in public places like malls or busses).

But seriously, have you met anyone who is used to living without AC as they enter the USA and all of our AC? They actually and actively complain about things being too cold all the time. Its a point of discomfort, not a thing to make a Youtube video and brag about.
