RE: copper pans.
I've never owned a full copper set, But I do have a couple copper bottom stainless skillets. Way better than anything else I've tried. I tried a ceramic "Green pan" one time. It was good for a while, then my wife (who cooks too high) scorched something to it. In a moment of desperation and frustration I used a brillo pad. Ruined. Stuck on every time after that. Also, sticking is usually caused by uneven heating. If you have a coil type range, they often become uneven over the years. If you have the other type of range or gas, use a copper bottom stainless pan and make sure its heated good throughout and it won't stick with a little oil.
Next time, grab his plate back like the Soup Nazi and go wash off his steak and slap it back on the grill to cleanse it.
