Why can't fortune tellers be stewardesses?

Is it true that the stewardess can't get married?

You can't marry a stewardess if you are single!

Flight attendant, that sounds wonderful, but I don't know how much trouble it is to marry a flight attendant. At home, basically can't count on her, in the days of flying to sleep, the poor man has to be busy inside and outside. If you want another child, only poor full-time men and nannies will look after the children for years.
