Another reference was in the pub where we could see spitfire planes attached to ropes, which were attached to the ceiling. This again is a reference showing that it could've been based around the war time as spitfire planes were used in the war.
A final reference about social context is when we see a cupboard filled with rations for the soldiers that were involved in the war. This shows us that they have stocked up on food as they are thinking that maybe there could be a third world war breaking soon. This also links to the war.
Overall, I feel that there are many references of social context and a majority of them link to the war.
