Do you know what I like about trips to London? The trains. And do you know what I like about the trains? The serviettes. Especially if you travel first class, as you should if you’re going any distance and want to end up less stressed than when you set off. Ours being a Virgin train, these were not normal serviettes. They were big and thick and red and had more in common with with bath towels than paper tissues. They could be put to a multitude of uses. Douglas Adams would no doubt approve.
