I don't drink alcohol at the airport except for having a couple of Guinness once at Manchester Airport and a pint of Carlsberg at Abu Dhabi once many moons ago (£7), I don't want the risk of continuous pissing on the plane through beer and I'm more content with a Burger King and a coffee ....lol
But Flying Long Haul I can enjoy my fair share of 'free' Red Wine on the planes which suits me fine...
