I run my own business and prefer not to work for jdubs. jdubs typically are cheap and think they can do things on their own. Once I told,a witness that I wasn't going to work for him anymore (he was a horrible customer). He took it personally but I continued to treat him (on a personal level) as if nothing had happened. Eventually he apologized and asked if I would accept him as a customer again. (He promised to be reformed). i reluctantly accepted. So far so good. Hopefully he learned his lesson.
There is a witness mentality that is hard to explain. It's similar to an entitalment mentality.
