I see this every summer on the subway in New York as women bring fleeces and sweaters with them to make sure they don't freeze to death on a 5 min train ride just because the AC is on.
Also, if there is 10 minutes of light rain forecast for 4:30pm on a given day, they will wear a waterproof jacket the whole day. Zipped right up to the neck, even if it's 90 degrees and extremely humid. On the subway platform, which is always 10-15 degrees hotter than the street and completely free of rain. I'm standing there in t-shirt and shorts fantasizing about how much cooler I'd be if I didn't have skin, and these women are zipped up tight in unbreathable fabrics based on their fear of a light shower hours in the future.
People in America are, in general I have found, entirely contradictory in their perception of heat depending on the time of year. In the winter, they're heating their homes to a temperature which, if it were summer, they'd be blasting their AC's to avoid. And in the summer, they're cooling their homes to a temperature which, if it were winter, they'd be cranking up the heating and donning sweaters to escape. I rarely experience any middle ground when entering a building. The preferred temperature is, I gather, the extreme polar opposite of whatever it is outside.
