> Italy and Spain have AC everywhere

Southern Spain may, but it's virtually unheard of up here in Galicia/Asturias/Cantabria. Even many businesses in these parts don't have AC, and our Ourense region has pretty regularly had 40+ C days the last ~5 summers

In the Canary Islands, where it’s not just hot, but also humid, you’ll be pressed to find a restaurant with AC. Some businesses do, but frankly it’s quite rare, and often times I’ve entered a business and felt a slap of heat in the face. Quite different from Madrid
