The joys (?) of being self-employed.

The opportunity came up seven years ago to take over a business.  We thought it was a good idea and leapt in full of enthusiasm.
I think that enthusiasm would have been somewhat dampened if we'd had any idea that so many ignorant freeloaders would drag us through court for so many ridiculous reasons.
First with there was the short guy with a toupee who took us to small claims because "we did a service on his vehicle and then it blew up".  He got nowhere fast.  The small claims court denied his claim so he took us to real court ... where the judge denied his claim.  He actually got removed by security for yelling at the judge.  That was memorable!
Then there was the nasty woman who tooks us to small claims court because "we charged her too much".  In the end we had to pay her $50 of her claim for several thousand.
After that came the guy who did vehicle repairs at home in his garage (on the side of his actual job).  He didn't do a very good repair on one vehicle and it came to us, then he took us to small claims court because "that was all our fault".  He didn't win either.
Over the last few months we've had issues with one of our staff.  In the end he quit and walked off the job ... then raised a personal grievance with us for unfair dismissal, as you do.  After SEVEN hours in mediation with the department of labour, HE has to pay US.  The process, although extremely stressful, was rather entertaining.
My question here is - is it worth it to drag people through the legal system just because you're an idiot?  I think no.
