I can vouch for G-Unit, he is what he says he is.
I get the impression he may be fishing for a bite or two.
Whilst i agree cabin crew do more than serve drinks etc I don't think the current situation will generate any public sympathy for your cause.
Richard Branson has a history of getting what he wants (most billionaires tend to) and I am in no doubt he can be a manipulative person to work for/with, the point I suppose is, if there are people prepared to work for him at the rates he offers, why pay more?
