I am sitting in the last coach of the train from Edinburgh to London. It is designated for smokers. Seeing only a few people in it, I assumed there would be a few smokers to spoil my journey. However, people sitting elsewhere in the train come back here for a hit or two. Some of them come often. I could have guessed all this, but I did not. My error in judgment notwithstanding, I cannot but feel contempt for these people. Cheats! Con artists! Turncoats!
