What is for sure is that US practice is to overcool indoor public spaces. Probably this is because so many Americans nowadays are so fat. The practice is wasteful of energy and adds to atmospheric CO2. The human body in good health can perform perfectly well at temperatures up to 25C or so. Setting the AC at 20 or lower is unnecessary and if you are in a draught from one of the vents it may feel far lower.
My sympathies are entirely with the women here.
I encounter this a lot in some of the larger public buildings. Especially in the climate I live, it's typically 105° to 110° outside, and these larger buildings seem to have their AC units running constantly to keep the temperature at a reasonable level. Movie theaters seem to be like that.
