Dogs (must be carried on the escalator)

390 STRANGERS to London are sometimes a little awed by the relentless efficiency of the moving stairway. They assume that the Londoner who steps on and off with such lack of ceremony must possess some special agility. Once safely launched, however, and gliding proudly down to the platform, self-congratulation is merged into anxiety and a discreet positioning of the feet for a good landing ... It is in this state of nervous tension that the stranger forgets to stand on the right and the hurrying Londoner feels his sympathy drifting into exasperation.
