I Flew AC536 OGG-YVR last night and near the end of the flight I was a bit hungry and I thought I could press the call button and summound one of the cabin crew. I was sitting in Y and it was of course dark and quiet because it was a red-eye flight but I was inspired by this thread, do I do it? I kept wondering if I had ever done this before in the many decades I have been flying. When I flew as a son of an employee I never did, that was just unthinkable, you get on, sit down, shut up was the rule, never ask for anything or accept anything. But in the past twenty - five years of revenue flying I have never pulled or pushed that button. I was sitting alone in 19B, three seats to myself, enjoying the space but I wanted a Kit Kat. So I reached, slowly albeit and I touched the button, which caused me to stop, a certain feeling of fear combined with guilt or privilege came across me and I quickly and sheepishly pulled my arm down, hoping no one saw as I could not go through it, I did not push that button. I sat there feeling guilty for even thinking of such a thing. As karma would have it, the service director came down a few minutes later to ask me if I enjoyed the flight and if I wanted anything. I said I would appreciate a Kit Kat bar. He smiled and brought me my Kit Kat bar and I had an overwhelming feeling of relief and pride that I did not push that button.
