Sadly, none of the main crew have experience running the galley in club, which is very different to running the first galley, so yes unfortunately it's is "a sink or swim sort of training" A ground manager said last week, it will take time to bed in and the crew will get used to it !! If that's not "sink or swim training" I don't know what is !!
The crew who had the experience running the galley were the pursers in club and as they have been removed from club, there is no one to watch who has the experience.
Also as each crew member has specific tasks during the service, it's not always possible to watch what is being done in the galley.
In my experience the service hasn't fallen apart, it's taken longer as crew are still learning to run the galley in club including the CSD who is juggling the extra duties with the ones they already had.
Capacity bucket is full and over flowing for the crew in club, who are struggling to find their feet with the most radical changes in a very long time.
