Everyone has dealt with that one crazy customer. I had one who had me carpet over the stool opening in a bathroom in a new house so their 3 year old would be "safe". I suggested that if she was worried, she should just lock that bathroom door, but no. On one of the stairways, I didn't know if it was to be wood or carpet until the last day. She bought the stuff to do either one. She had a carpenter put up all this fancy wood trim just the way she wanted it, then changed her mind and had him tear it out and start over. The bricklayer was half done with the front of the house, when she decided she did not like that pattern after all, and wanted him to tear it off and start over. He quit. She was a school counselor and her husband was a psychologist.
