While travelling in some Asian countries, I discovered that in some areas students flood the classic Starbucks so they can study in controlled temperature environment (no for socializing). As a European, I only understood late in my life how crucial was AC to boost the economical development of some countries like Singapore (among other things of course). Where would many European countries be without heating?
