STK - I am EXTREMELY confidernt in our abilities to correct such problems. We just don't prefer to take on such assignments as long as we have plenty of other work. Sometimes we do get calls from other friends in various trades asking us to look at tricky situations involving their friends or customers with a "do you think you could do anything for these people?" question. In those referral situations, we will often go take a look and offer whatever advice/services we can. We work in a lower budget market and many local homeowners opt for uninsured, cash basis contractors or for well-marketed, high priced, will finance operations and then get stuck with shoddy work or uncompleted jobs. We typically work on our own projects and try to avoid rescue situations as it is easy to succumb to the desire to be helpful and "nice guy" yourself right out of business.
This does not appear to me to be chatter, rather it looks to be scratches. If they were confined to the edges of the room, that would definitely be edger marks. However, given the description that they over a large portion of the floor, I find that confusing as why would there be edger marks anywhere except at the edge? Regardless of the source of the scratches, the answer is the same - sand them out
That GC should be on the hook for that work because he should have checked the floor before the finish went on. Personally we wouldn't put finish on until the customer has okayed the stain color on the floor itself as any sanding/staining issues must be handled before the finish is applied. Picking a stain color from a tiny piece of paper is a recipe for disaster - especially if you're trying to match an existing finish.
Each person has limited resources, whether we're referring to financial, emotional energy, time or any other category. Fight the battles which matter to you, so if this floor screams at you every time you look at it, take action. If it is just a surface you will cover with rugs and furniture and children running to the backyard to play catch, renegotiate the money and go coach the baseball - better yet, grab some more folks and go join the fun.
