Quite rightly too imho - or are you saying that cabin service should come before safety and ignoring written Company orders (JPM's) is ok?
This was never a problem when working one (or two) down before, so why should it be so now? Any SCCM unable to take 5 minutes out from their cabin service role once per hour should consider asking their manager for a time management refresher.
