I've never turned away clientele based on race, religion or sexuality, quite frankly I welcome everyone who is welcoming to me, but I have opted out a scant few times based on things such as unsanitary conditions or my belief in their intent & ability to pay me, or even people who were just extremely rude, argumentative over invoices and obsessive-compulsive in their unreasonable demands. A trail of unfinished work by previous contractors is usually a good clue
. Does the law stipulate that I was prejudiced against them and that I should be held accountable for 'damages' or mental anguish?
Then again I've also turned down work that was either too big or where I'd be unable to finance a significant materials outlay (or if I had, I would be personally ruined prior to anything getting to court if things went south such as a client recievership)
