For the past 12 months, she had proudly taken to the road as part of an all-female driving school. But Emma Sherdley is not exactly all woman.
Until a few years ago she was a married father-of-two called Andrew.
She is, though, in the middle of treatment to change gender and has the legal paperwork to prove it.
But that wasn't enough to satisfy one client who claimed he had been shortchanged when he booked a female instructor to teach his wife how to drive. He phoned the Laugh 'n' Pass driving school threatening to sue after Miss Sherdley, 42, turned up for the lesson.
'You have sent me a man. Send me a proper female. How dare you send a man with a deep voice,' he told Joanne Dixon, who runs the school in West Yorkshire.
The man, a Muslim from the Meadowhall district of Sheffield who has not been named, claimed the company deliberately sent a man disguised as a woman.
