Most have trouble with the concept of grading. I had a customer maybe 12 years ago who had way more money than comic knowledge. He would buy books and go "this is a slam dunk 8.0" and I would have to rain on his parade pointing out everything that was wrong with the book. Then when the grade would come back the one I predicted, he would get mad at me. Needless to say after going round and round a couple of times, I asked him to find someone else to submit his books through. He stopped posting here many years ago, he probably found a more secure way to grow his capital. Sadly, his is far from an isolated story.
