Hardly a first I fear. It was done 30 years ago.
My partner was a Cornish Pub Landlord when she changed to become a Landlady back in the very early 1980's.
It caused a little stir at the time. Article in the Western Morning News and a couple of reports on the Local radio station but it soon died down.
I didn't meet her until several years later, and we've been together for 22 years now. I've actually written a fictional comic novel based on her exploits, some of which were absolutely hilarious but neither of us have ever had the courage to let it be published.
