Not BA related, but I have a very fond memory of flying SQ F from NRT-SIN back in 2011 (the day before the awful tsunami IIRC). It was an overbooked flight, and They had only loaded minature bottles of Krug for some reason and they went pretty quickly. Then the Dom ran out shortly after. I sometimes enjoy a G&T whilst flying so indulged in a few of them. What I loved about SQ was that they expect and encourage you to use the call button if you need another drink. Except in my case, when my seat was almost flat/deep recline, the call button wouldnt work. The crew apologised profusely, and commented that my average G&T consumption time was approximately 20 minutes so they would return with a freshly made one based on that interval until I said stop. And that is exactly what they did ..... Only on SQ!
