Some of my foreign students have asked me to advise them on form and etiquette.
As your career progresses and you are asked to mix with people of great wealth and sophisticated society, it is helpful to know some of the more subtler nuances of British Etiquette such as dining manners and social manners and graces.
This can be taught through the medium of elocution and can be great fun sitting at a table set in my apartment, or in various locations agreed by you.
