This is one of the problems with the internet, you cannot say things in jest as you don't get to see the person when they are typing so it ends up coming across all wrong.
And whilst you may be able to speak several languages, and have a degree, sadly there are a lot of cabin crew who are not exactly the sharpest knives in the drawer which are the ones I was thinking of when I was typing. Unfortunately I am guilty of doing something we all do from time to time, stereotyping people just as flapsforty has done in his/her reply.
