I bet you - each and every single flight attendant once answered while being asked - why do you want to become a flight attendant? - with:
"Oh, I love learning new cultures and people from all over the world".
But very few will actually know what such a statement means - It can be really, really, reeeeeaaaaallly frustrating and challenging sometimes. So flight attendants that quickly flip off with passengers from a different culture from theirs really makes me upset sometimes. That happens in my airline as well, so I always make sure to motivate my team and go through a few basics at briefings when flying to some "special" destinations. Tel Aviv is certainly one of them.
Not only because a kosher meal service can be a little bit challenging (for instance, each passenger has to personally open his own meal before you can put it on the oven and cook it - imagine this on a full aircraft), but specially because you have to be really very careful with anything you say.
PLEASE never ever repeat this faux pas I once heard:
Flight attendant: - "Would you like some water?"
Jewish passenger: - "yes, please."
Flight attendant: - "With gas or without gas?"
No need to say what happened next. Please bare World History while flying with passengers from a different culture from your own.
Oh, and if you are a female flight attendant, don´t be chocked if the first question you hear from a very strong religious jewish passenger is:
-"Do you have your period (yes, as in menstrual bleeding in case you´re wondering) right now?"
And if you give yes as an answer, don´t take it too personally if that passenger will despise you the entire flight. And please, don´t touch or talk to him neither - it will only make things worse..
