Victor Strode Manley, in his Regional Survey Of Warminster And District (several volumes compiled in the 1920s and 1930s but never published) included a selection of anecdotes that had been told to him by various people.
This anecdote concerns the village of Corsley, between Warminster and Frome:
The Royal Oak at Corsley is notorious for slow serving. The landlord said he was always glad when a charabanc passed by instead of calling. On one occasion a party was so annoyed at being served so slowly that some of them went behind the bar and served the party himself and paid the landlord what he liked. Another time a similar party called and some of the women asked for warm water for their drinks. The landlord went away to prepare it, but the water was so long in coming, that the party walked out without paying at all. Since then, whenever a charabanc is sighted, there is a hurried move to pull down the blinds in the hope that the inn will not be noticed.
