So out of curiosity, I made an excuse to use the C cabin loo (is normally allowed if the Y cabin aisle is blocked by a trolley) and glanced at the cabin temperature controls. There were two dials IIRC and both were set to 25C - no wonder the cabin was so hot! So I asked the CC member in the C cabin whether the temperature could be turned down a bit and pointed to the 25C settings on the panel and he said "sure, yes it is a bit hot, we were about to do it".
Can't believe you used the J loo sitting in Y.
