Very amusing thread. As a dentist, it reminds me of the standard lines that so many patients come out with. I guess we are all guilty of appearing foolish at times.
Why is there an ashtray built into the outside of all aircraft toilet doors? I can see how it could be mistaken for the handle. I suppose originally the designers wanted pax to "check their stogies" outside the loo. Now that most flights are non-smoking, shouldn't the ashtrays be (at least) taped over?
My favourite gripe is pax releasing seat belts and all standing up before the a/c is on final stand. Then they all stand there, pressed against each other like commuters in a Tokyo train, for several minutes. I still haven't figured out what they hope to achieve.
Full marks to cabin crews - I think you all do a great job in the face of overwhelming odds!
