An interesting story.
I have a standard contract I usually use with startups etc. that is written to be fair to both parties and vetted by multiple attorneys. One that I worked with insisted that I use theirs. When I went through it, it was clear that they took it from a template and there were numerous holes in it that I pushed back on. They stated that all of their other contractors used it successfully and I replied that these people must not have read the contract.
It was at that point that I pointed out that the jurisdiction, "Orange County Georgia" does not exist (they had obviously copied it from a California template or contract) among other things. Against my better judgement I re-wrote their contract and used it. They ended up being a major pain in the ass client that was really bad at basic communication. IE: would not answer direct questions in writing with yes or no answers.
Contract negotiations are often a sign of things to come with the rest of the engagement.
