Thank you all very much for your responses. Very enlightening. And not really any support for the theory that cabin crew believe that the higher temperatures make people sleepy!! Or that they have much control!! Shame - as that might be easier to rectify if we can just get the message across that most people find it too hot and will sleep better (and thus stay out of the galley and therefore out of their way!!) if it's cooler. But it does seem like it's horses for courses and if they turn it down, they will have complaints from those who are cold!! So I guess I'll just have to strip off!! That should make them turn it down!!
