Please try to keep in mind where he was. In a doctor's office. He may have had many things on his mind at that point that made him irritable. Maybe he was there for something very serious or a family member that ha something serious going on with them. Doesn't give him the right to visit his mood on you, but you don'tknow what was going on in his mind.
Your quilt is beautiful. Too bad for him that he can't see that. Think of all the beautiful things in life he is missing out on right now. Don't you kind of feel sorry for him? Shake it off and move on. You have a quilt to be very proud of!
