When I was growing up I was taught that people much older than me should be addressed by their title e.g Mr or Mrs...... Now, when dealing with shops, firms, office staff etc. I am addressed by my first name, and I don't like it. I think in the first instance you should be addressed 'Mr or Mrs' and asked it is OK to use your first name. And I say NO.
Am I being too old fashioned?
