The gentleman that came at 7pm was unfriendly. The washers were missing from the hardware package. He should have checked that ALL the hardware listed in the directions were there before beginning the assembly. Now I'm waiting for the manufacturer to send out another hardware package, it is scheduled for shipping on April 15. The worker also refused to remove the box and garbage which is part of the service I paid for.
I called Wayfair and they were just wonderful. They couldn't have done more. I am very happy with Wayfair and will continue to do business with them. The issue was the "professional " assemblyman.
