This makes me madder than hell also.
The other day, I boarded an airplane at LAX, early in the morning, after the plane had just arrived from another city. The airplane was appropriately cool and as the passengers boarded, they complained to the FA that it was too cold. Even the FA said it was "freezing."
So what does she say? I'll get the captain to turn up the heat as soon as we can."
We go from a comfortable cabin to a sweltering sweatbox in a matter of minutes. Stupid A-holes. Put on a sweater if flying makes you cold.
This happens on at least half my flights. Some idiot wearing too few clothes complains that the cabin is chilly and the FAs oblige. I complain that it's too warm and the FAs tell me that the other pax win because they were too cold.
