When I asked you to fix things, I am not expecting you to bring tool, get sweat and may end up ruining the thing. The least you could do is picking up your phone, dial the repair man, watch him and pay him when the work is done. I'm not even asking you to do it right now. I give a one week gap. But even that, the schedule is too tight to get just one thing done.
So don't bother screaming that you won't do it. Because you didn't do it anyway when you said you would.
