There was a time when I used to pass through Shannon airport on a regular basis; so did Fidel Castro. In those days, the flight from Moscow to Havana would come down to refuel in the west of Ireland and the passengers would sometimes get off and have a stroll around the airport. Once the bar tender told me that Fidel had been there a few days previously and had enjoyed an Irish coffee made especially for him by the bartender himself. The great revolutionary leader had liked it so much that he had sent one of his companions directly to the duty free shop to buy a case of Powers. This was rapidly loaded onto the Aeroflot jet, which then sped off to Havana.
