As one flies longer as a cabin crew,one tends to pick up lots of bad and offensive habits from some of the passengers (I said some and not all ya).
We,cabin crew (well not all I supposed) learned to be impatient just like some of our passengers.Out of uniform, we also tends to act like our passengers and become impatient,demanding and critical of the people serving us. Just like the saying goes "Imitation is the sincerest form of flattery", we also act like our passengers by being ya ya papaya with those who look after our welfare or serve us.
There was an incident when a crew got so mad with a waiter for making him wait half hour for his meal that he shouted at the waiter and stomped out of the restaurant.
Another crew screamed at a fast food server for giving her chicken breast parts when she told them she hated them. "You idiot didn't I tell you I hate chicken breasts?!" she screamed on top of her voice.
A stewardess shouted at a guy and used nasty words on him when he jumped queue at a taxi stand.
A bank teller friend told me of how nasty an IFM was towards her. He barely had more than a few hundred dollars in his account.
Where did all those I've described above come from? Passengers,of course!
One thing we don't do like some arrogant passengers did was to slap or spit at people serving us,thanks to our ability to realise how painful it will be if we are sued.
