I can understand that in some instances. The owner of my school is very very cheap (not frugal) and hates to turn on the A/C. I insist that it is turned on in the summer. When it is 35C with 20 people in a small room, the fan doesnt do it. So I can see if the house is unbearably hot and she asks for it to be turned on. If it is just a little warm I can see how this seems like a ridiculous request. In the end it is the employers decision, but I think she is not out of line to request that.
