To the industry participants who reacted negatively to this post...Yes, Klaus is a great guy, and he most certainly has earned his reputation as a standup business person who delivers a wonderful product and service at a great price. But if we assume this poster is telling the truth and did reach out on multiple occasions to contact him with no luck, what is he, as a customer, supposed to do? In no way does he disparage Klaus' name in the original post above...he's simply looking for a way to reach him from people who might know something he doesn't.
Yes, it is reasonable that this "fix up" job should not be a priority for Klaus, and it is certainly a kind gesture on his part to accept the work. I think the poster (Clayton) himself understood and would admit to these points. But once Klaus accepted the job, the customer should be treated like anyone else.
A customer – any customer, whether they spend $100 or $10,000 – has a right to be frustrated with the crickets Clayton allegedly received (assuming, again, that he's telling the truth). I say this as a business owner for more than 20 years; if one of my customers took to the boards with this kind of question – in the tone it was asked, for the reasons it was asked – I would completely understand it. Ironically it appears that Klaus is the one "industry participant" who seems to understand this, judging by his measured response in this thread.
Not every poster who asks a genuine question in frustration on a message board is ungrateful and unreasonable; let's not paint them all with a "you have no idea what it's like to run a business" brush. Sometimes you, as a business owner, are not the victim. Sometimes you drop the ball and should be accountable for it.
