The Writers' Circle

My first real job was as a hire counter sales assistant working in a plant hire company.
Then I moved to work in a prison library and I used to joke i was the only librarian in the country with a certificate to change abrasive wheels. 
It certainly raised a few eyebrows amongst the prisoners the day one of the workmen brought his still saw and an abrasive wheel to the library for the wheel to be changed.

While working at the prison, I trained as a hostage negotiator, and when many years later I trained as a florist and opened my own shop, the joke became that I was the only hostage negotiator trained florist in the country.
