All later evening departures has had some sort of adaptation to the service in one form or another to prioritise getting the lights off as quick as possible for customers to sleep. There used to be a post 20:00 departure service standards which differed from pre 2000 departure service in CW(e.g. one less bar round, more elements to be completed on ground etc , sleeper/ goodnight service variations).
Then came a time where for evening departures, everything was delivered with lights off and hand run rather than from a trolley, with crew delivering using torches in CW.
With the re-introduction of full service in Aug-Nov 22, there is now a goodnight service on all departures post 21:30 local in CW WTP WTP. However, the difference is a full experience is now available as an option for post 21:30 service in CW too for those who want it, but the objective will be to settle those who wish to rest quickly/ maximise rest, and then provide the full experience to those who want it. If it's a minority, this would be completed with lights off.

On very late night departures, it'll be a light snack service for the first service.
