Lord snot, No one should be bullied or be talked to rudely, this should not be happening in the aircraft, team work remember! If someone feels like they have been treated badly and your not there to support them, then I assume you would not be suited to a cabin crew job.
Leave them alone. Nothing nice to say? then don't embarrass yourself by posting here,
good on you guys, its nice to see people putting there foot down
Everyone is entitled to a question, no matter how silly it may be. Were all new once!
