Thanks so much for the kind and ecouraging reply, OzyOs.
I'm not comfortable posting the name of the airline here in the public forum, but you may PM me about if if you like. During the screening, each girl was individually called and assessed physcially.When it was my turn, they asked me a question or two, then asked me to smile for them. When I did smile they sort of pulled in closer to scrutinize my teeth etc. and then that's when they told me that they couldnt accept me because of that.
Anyhow, I was actually not offended and welcomed the remark as I prefer knowing what I did wrong so I can improve on it for applications to other airlines, such as Emirates, for example.
The girl who went before me passed the smile test but when they asked her to remove her stockings, they remarked that she had varicose veins.
