I'm surprised he could be arsed. I certainly wouldn't, mostly out of principle of demanding a second name change being irritating considering the fact I would have just done it for you, as it just shows you aren't thankful and don't care about it, and can't even be arsed to think of a good name you want to keep.
As for the question "Is this worth my time to even read this thread, yet alone post?" No, no it isn't. But you have already wasted his time, so feel free to enjoy knowing you have wasted mine also.
