I don't care if they were passengers or crew; I'd complain; quite loudly in this case as it was crew. Love & being in, is perfect & lovely but hey, not when it kicks me awake AND I'M NOT INVOLVED! Way too intimate for me & even worse that it was crew; sorry, just so not right! The fact that the rest of the crew thought it was acceptable behavior (their jokes/comments implied as much) is way beyond tacky; where was the supervisor/purser? Imagine Starbucks, Safeway or Target staff making out in the aisles or front of the stores "on their break"; eeeewwwww! I'm fairly certain this behavior is absolutely NOT ALLOWED/PERMITTED/SANCTIONED.
