So my return LIS-LHR was not as good as the outbound flight. CE was back to the exit row and the entire plane was full. Only 3 crew in CE, with no drinks before the meal service, which started an hour into the flight. Two crew did the meals, with single crew doing drinks after - which took an age. Plus they were rationing champagne - only half glasses being served, no bottles…crew were very apologetic at the lack of drink stock.
