How many people on this forum do retail work, and deal with GC's that work nation wide?

I am curious and intersted in you horror stories or good ones, and how did you deal with the horrors.
Inch thick plus contracts. Promises of when you will be paid. Projects Mgr's who are behind in there paper work. Soooooo change orders dont get signed, payments are late, or how about all the freakin lien waivers you need as a sub to get paid?
