Thamesdown in clean bus shock

If I were responsible of publicity at Thamesdown Transport, rather than making a fuss in the local press about the fact that they now clean the interiors of their buses more than once a day, I’d be rather ashamed that they’ve been allowed to run in such a filthy state for so long. The drivers of buses of some other companies (admittedly not local ones) have swept their buses regularly between journeys for many years. In comparison with the cost of a new bus, a broom and a couple of minutes of driver time would be insignificant.
