"This part of ultra orthodox Judaism; the men simply do not know how to communicate with women in a position of authority."
It would be nice if passengers primarily considered cabin crew as just that, rather than men or women.
The attitude seems to extend to women in general. That would explain why when the man sitting next to my female colleague wanted to get out of his seat he jabbed her in the ribs to get her attention and then gave her a dismissive hand gesture to tell her to get out of his way. If he is quite so wedded to such archaic cultural practices perhaps he should travel on a donkey next time.
