I feel the use of first names all the time is another sign of th erosion of respect for each other in society. It imparts an informality to what in many cases, is a serious and difficult time, I.e. Receiving bad news at the doctors etc. This might seem an old fashioned view, but in my my view, it is much better to start on a basis of formality, Mr, Mrs, Dr, etc, and then move on to first names if appropriate once a relationship has been established between the two parties concerned. It also avoids the embarrassment of using I liked names - I never use my first name, but our current bank manager called my Martha at our first meeting - if he had called me Mrs Gaunt Imowuld have asked him to call me Louise, avoiding me having to correct him as our first ever interchange. Bring back a bit more formality in my view, in terms of address, dress and behaviour!
