Inviting customer feedback - how do you handle this double edged sword?

Yet another thread on how picky/pushy customers drive me nuts.

How do you (or DONT you) encourage clients to make comments/edits on the photos? I once thought a full invitation and assurance that they'll have the opportunity to request changes/edits was a good thing, a sign of good customer service.

But recent experiences it opens up huge cans of worms. Even with proof delay, I'm spending so much time responding to comments/explaining/making edits on edits. Many have to do with the fact that they're looking at them on uncalibrated monitors, I suspect. How do you cope with this?

Three images from a recent session would have been unusable in film days (underexposed and WB off) but thanks to Lightroom I was able to salvage them in B/W. So of course, the client wants to order them in color too, so I reluctantly showed them, but now she's informing me the color's strange and I need to fix it. Yep! told ya so.

I know it is my duty to produce images of perfection, but I also don't think in film days, photographers were so vulnerable to the armchair quarterbacks.

I'm contemplating not mentioning the "you can place your comments/edits under the photo" feature at all in the future, and figure that way only glaring retouches/edits will be brought to my attention (please remove big zit, etc).

I just don't charge enough (even w/ recent price hikes) for this nonsense. I do think my end product speaks for itself, and I don't need help from the customer to get it there. (I fully admit there are times I need fellow dgrinners help, and I know when to seek it).

Thanks for always tolerating my rants, and offering me your vast experiential wisdom.
