On a recent flight (can't remember whether it was back from GIG or JFK ), the economy announcements were accidentally left on in Club - clearly someone had headed off to find the culprit, as about half way through the menu (chicken pasta or a beef casserole IIRC) the announcement tailed off and you could hear the exchange between the crew along the lines of "no, it's definitely traveller only"....

Tasty as the econowotsit meals sounded, I was quite happy to stick to the printed J menu
