I received an interesting call the other day from one of our customers regarding some posts that were on a popular forum.  The call started as most do, asking for some information about some of the products we sell.  Once I had answered all of his questions, he said he wanted to apologize.  I was caught a bit off guard, and inquired what he was apologizing about.  He was worried he may have offended me with a couple posts he had made in a popular forum regarding our company, and it's deficiencies.
