On most recent purchase of buffet, he was very helpful.  Already had to get a part replaced that was broken.  Then he found screws that were too short, a flaw on top of buffet, and wrong assembly instructions.  Handyman found some of his own screws in his vehicle and cut them down.  Had to reassemble some parts due to wrong instruction sheet, and put the flawed area on top of buffet toward back so it would not be obvious and used a sharpie to color the area flawed.   It turned out ok because of his expertise.
