In order to spend more time with customers? Such enhancement rubbish. In my long experience of BA, the majority of crews will serve quickly to spend any free time chatting in the galley, incl the captain for 20 mins on my last flight. Long ago when LHR - AMS was scheduled as a 60 min flight, it was often 40 mins in the air, and they still managed to serve a 3 course tray which included a small fillet steak, with a wine run. You might even get a coffee if seated in the front rows.
