Gesan, I can only speak for myself but I will try to answer your question. I happen to feel the other cuemaker being referenced has NOT given the effort that he should have to satisfy his obligations, and has not handled his situation well at all.
The key difference though is that the other cuemaker accepts full responsibility for his shortcomings and has promised to make everything right, albeit much slower than he should. Because of this I am "cutting him some slack," instead of bashing on him for his downfalls and the lack of speed and effort in which he is getting it handled. At a certain point though enough will be enough and the courtesy of the extra patience being shown to him will wear thin if not taken care of.
Now Mr Griffin on the other hand is not accepting any responsibility for a situation that is entirely his fault, even if it were beyond his control. He is choosing to be difficult to work with, and is trying to work the deal so that all of the inconvenience will lie on the customer instead of himself. In fact IMO, he is even trying to scam Snowmon34 for more money so that the customer ends up helping to cover any costs or inconveniences resulting from problems that are his.
