Many store fronts have large sliding glass walls that open up the entire structure to open air - and they blast AC at 16 degrees inside, while the entire store is open to 30+ degree air outside.
The idea is so that the AC would leak out the doors and entice people to want to walk into the store. But that means that all the AC is wasted.
This kind of irresponsible use of AC is everywhere in hot climates in large shoppping streets, pretty much everywhere - North America, Asia (in asia it's insane how much AC is wasted), and I don't see it as much in Europe but probably some stores do it.
That's just a waste and is really sad.
