I find this very strange.
Usually, the cabin temperature is a great deal colder than Mrs Bealine finds comfortable and she always wraps herself in a blanket. I find it tolerable, but verging on the cool side.
Mrs Bealine used to be a cabin crew member for Dan-Air, in the distant past, and she always explains that the cabin temperature is set slightly cooler so that the crew can comfortably work. (No one wants to see crew members serving their food with damp rings around the armpits, now, do they?) Uh- oh - that remark will probably have Pucci reaching for her hairbrush!
So, I find it strange that crew members would want to jack the temperature up high, unless of course, they don't yet know any better.
