English co-worker arrives at work drenched in sweat because, thanks to the sciopero, he had to walk to work and was wearing a black synthetic shirt. Female Italian co-worker walks into our office (which is the coldest room in the entire place because we're foreigners and we like AC) and says to him: You'd better shut off the AC immediately or go outside and wait until you dry off or you'll catch your death!
He and I exchange glances and chuckle saying "No, don't worry, we're foreign... we're immune to AC induced illnesses".
Later that day I walk into the secretary's windowless office and it literally feels like a sauna. I look at the AC unit and it's off so I ask why. Her reply: "Yesterday after leaving work my stomach didn't feel well from all the AC, so I decided I'd rather not use it anymore".
