At the risk of making a serious point, and while stepping delicately around the earlier posts:- shouldn't anyone who plans to go into an industry as service-based as aviation do a mandatory stretch in McDonalds'or wherever?
You will be a better effoh or captain if you can empathise with the cabin crew, and have experienced front-line customer service. And it does no harm either to realise, as you check into your five-star billet down the line, just how little service staff get paid, and how hard they work.
