You should read the stuff I have on a large UK Sports store that I took to court and won. Now that is interesting stuff. Because I knew beforehand I was going to have problems, I documented everything. That includes the stuff the guy who was leaving told me, the scientific reports they refused to look at, the attitude, and the remarks made by the judge.
It's all made up in web-ready form, unfortunately I don't know yet where I stand legally. Because I won the case, and it is all fact, I could publish it. However, they are a huge company and could walk all over me for minor issues, so I have to tread carefully.
