I have received several mails and friends questions about the reason behind the (Dear Guest name). Simply, any one of us is a guest, whether for a few minutes buying grocery at the super market, a few hours on board a flight, a few days in a fancy hotel for a long waited vacation, a lifetime commitment with your bank or mobile operator or even reading a magazine as such, your expectations of the quality of service should not be compromised, so I came to the conclusion that every one on earth is a guest or on the other meaning customer being served by some one else.
