Just a point of order, they would have struggled to go to met brief together. There wasn't a met brief to go to, you self briefed because everyone had a different reporting time. For longer flights, it was normal that 1 crew member went over for a face to face brief with the met man. Usually but not always the captain.
In flight meals?? You are having a laugh of course. The squadron claimed money and bought flying rations that were kept in the crewroom. The crew sat and ate those very rations before the very flight. At the same table I was sat on, so I can confirm they did eat. If you need that under oath, I can comply if required.
