I was travelling home yesterday, changing trains at Twickenham, when I noticed a smartly dressed man, who then proceeded to spit four times as he walked along the platform, which I have seen others do elsewhere, at least he did it onto the tracks. Then a bloke sitting next to me sneezed and did not either cover his mouth or use a tissue, so some of his spray went on my slacks. I had also been subject to having to overhear two people talking on their mobiles for at least 20 minutes on a previous train about unimportant subjects. What other bad habits annoy you? Am I being a grumpy old man?
