I heard about the coffee woman sueing McDonalds. There was also a guy who won a case after getting bit by a dog on his a**, after climbing the fence and shooting the dog in its own yard. Then there is the woman who won a case against an rv company, because they didn't put that you can't leave the driver's seat while it's on cruise control. The company decided to go ahead and put that in incase she had relatives who wanted to buy from them.
Yeah, to sum up, better avoid supermarkets and driving with traffic.
Seems just about the only way to avoid ignorance is to become a total social recluse.
