Wycombe. I hope I dont come across as cynical but its damn easy to make the obvious customers (FT's and parents with children) happy onboard - and off - when you actually have no other duty to perform inflight. Give any of the Flight Attendants 12 hours on a AKL-LAX service free of any workload and I bet you will be pleased as punch with them also.
Many of the Concierges do jump on the end of a bar-cart and get involved but by their own admission that is usually to alleviate the boredom of having nothing else to do.
And the 7 that did leave due to conditions, have now all been replaced.
