It don't really see what the big deal is. Why should one rennovation bother you? Don't you bid on 5 a week? Get over it and forget the powwow. It is not worth losing a good paying customer, because your feelings are hurt. And as far nit picking small things... either make sure they fit into your schedule or charge them what its worth to put up w/ there crap.... supply and demand.
What the hell are you talking about a loss leader for? It sounds like it is a profitable account... not following any of you points.
