I believe the kind of common sense you are talking about was removed by airline management around the same time they removed the cabin dressers and 45min turns..
Don't know about you but there is no time on my turnarounds to eat anything, too busy pulling snotty tissues out of seat pockets and cleaning up vomit before the next load of pax board.
Trust me, it's not my choice to consume a meal standing up in a galley where a sensitive passenger might be offended by my consumption of actual food. But policies like not being allowed to draw a galley curtain, having barely enough time to pull rubbish out of aisles before boarding the next flight and no controlled rest don't assist my ability to hide the shameful act of eating.
