Posh women who ask for daft things like Ukranian vodka with cranberry juice and find it "astonishing" we don't have it on board... or people who moan that there's only 1 type of beer on board, or people who find Chardonnay "simply ghastly" and can't drink it "to save my life" only to guzzle as many bottles as their table can fit once they realise it's free..... especially considering they've paid about £50 return for the flight.
