Frankly I've had it happen to me a number of times, but it irritates me each time nonetheless. I do what I would like to think of at least as good, if not exemplary (or great at least) work, so please don't bitch, complain, or moan about my work if you can't or won't do it yourself.
If I tell you that something cannot be done, it means I can't do it. While that may change, and while I could be wrong, it's in your best interest to trust me as the professional that I know what I'm talking about because chances are you don't have a clue.
And yet...even as the professional, I've had to deal with this a number of times...woo sah....*twitch*
...sew many things, sew little thyme for ewe and eye...
