I personally think that the right approach for an owner is to acknowledge an issue and commit to rectify it. I think that the forum understands that there is variability inherent in the business and anyone can have a bad day. I have seen a supportive response in the forum to this approach. Of course, crossing swords tends to invariably turn out badly and a non response is more prudent.
Note that we tend to be much faster in typing our frustrations than accolades and that should be considered also.
Just my 2 cents
