A good buddy of mine, who will remain nameless and, yes, I have some, always has a double vodka or two before an interview or simulator check ride. He reckons that the relaxing effect of the grog far outweighs any minimal diminuition of his performance. Of course he gargles afterwards. His career has been meteoric and happily successful. He may even fly, or have flown, for Riversands Rabble.
