I have done a trip with a CSD who couldn't be less bothered and kept complaining, not only at the aircraft but also on the bus to and from the hotel and of course also at the hotel, about having to work in the cabin for an eternity until retirement - where in the job description does it say that the CSD should be part of the service this CSD kept asking.
Our CSD also threw comments card into the hands of those passengers with a complaint. If they wanted to email WW personally with their complaint our CSD happily offered to give them his email address. On top of this - endless speeches to some of the passengers about WW bringing down the airline and wanting to screw the entire cabin crew community.
CW Galley Operator (7) also spent both sectors complaining about running the galley without being paid to do it - the pursers should do it - not main crew. A main crew actually works as galley operator in First without any problems - response from CW Galley Operator - that's actually an agreement between BA and the unions!
Do some crew even know that many airlines have main crew working as galley operators? It's actually happening not too far away - Deutsche Lufthansa AG is one of them!
