BA Crew standards

Went to Abu Dhabi for the 5 days this week using British Airways - I was stunned by the difference between the 2 crews.
Going out on the Monday, we were an hour late due technical difficulties, but the crew from the purser downwards were incredibly helpful - they regularly explained what was going on and did their best to make everyone comfortable. As a Goldcard holder travelling further back in the plane than normal, I was still picked for exemplary service including extra G&Ts, but generally the service was excellent, particularly to those travelling with younger children.
Coming back to London overnight last night, the crew were from the other end of the spectrum - zero service ethic and treated us like cattle.
BA will never succeed with such inconsistent approach to customer service.
