My pet peeve with aircon is retail shops. Ones that have AC but refuse to use it because of the costs (take my business elsewhere if I cant stand to be in their shops). And i'll stand around in shops that do have good ac, even if i'm not interested in their product range, if it helps me beat the temperature extremes (not sure if this is a good thing for them or not?)
Another funny story, when I visited a sub-arctic city in China, ALL the shopping malls had the AC set to about 30degC. So you go out with all your woolies on, then when you get in the mall, you feel the need to strip off (better have come in 'layers'). Then have to put it all back on when you go out again. Plus carry it all around with you in the mall.
