People like this are the reason I insist on 'Dr' in all walks of life, not just professional.
This is where the sexism really hits home. The fact that total strangers expect a justification of my sexual status I order that I can complete a mundane, prosaic transaction.
No one has been more surprised by this than me. Unless you've known me years, you'd be unaware whether the family name I use is mine or DH's, and care less, I would imagine. Not so. People have been extremely defensive and rude. Most recently was my car dealership, who refuse to address me by the title I specify despite numerous polite requests, which for some reason have been badly received and, needless to say, ignored.
Other than this, it's 'computer says no'.
I can't imagine why a simple assertion of an independent identity on the part of one woman should cause such gratuitous offence in other women. And yes, it is always women. Men as a rule don't give a stuff.
This isn't a new issue. I've been married since 2008.
