Curious as to what are some unorthodox reasons you have refused to see a client?
One thing I have done in the hobby (and in the dating world) is refuse to see men who are from New York.
It's a southern thing. Most people in Alabama don't accept that anyone would move to Birmingham from NYC for a legit reason. They have to be crooked, broke, & running from something.
I gave a reference last year and the provider called me back and said "WTF he sounds like Boomhower!" She ended up not seeing him.
