Do you use one? Does it annoy you when asked for one? Does it frustrate you when you HAVE to give one?
I don't use a prefix (Miss/Ms/Mrs/Doctor) ... I have my name and that is what I identify with. Any further form of classification is unecessary as far as I'm concerned.
I am married, but find it utterly irrelevant when placing an order for instance, after giving my name, to be asked "is that Miss or Mrs". "I don't use a prefix" I'll reply .... simple enough you'd imagine, but the amount of blank looks I get back, and often as not some hostility.
Or when ordering something over the phone ... "is that Miss or Mrs" .... "I don't use a prefix" ..... "But I have to put something in, the system won't let me continue otherwise".
I find it such an incredibly old-fashioned method of address ... what on earth does it matter if one is married or not .. it doesn't apply to men, why does it apply to women. It harks back to the days when women were considered chattle (still are by some blokes!).
