You can see them in every airport in the world. They are businessmen and women who have to travel for their work. When they first applied for the job, they may have thought of good food and hotels, huge expense accounts and fashionable cities. Now they have to sit in airport lounges, tired and uncomfortable in their smart clothes, listening to the loudspeaker announce “The flight to Tokyo, or Berlin, or New York is delayed for another two hours.” Some people say to me, “How lucky you are to be able to travel abroad in your work! You can go sightseeing without paying any money by yourself!” They think that my job is like a continual holiday. It is not. There are advantages, of course, and I do think I am lucky, but only because I can go to places I would never visit if I was a tourist.
