Short order is harder than it looks.
Best morning I ever had was a little over 600 servings of eggs to order for breakfast in Korea. I loved working the flattop. 5 or 6 orders up at once, keep 'em straight, and greet everyone by name (on their name-tape). Good times.
I'm too old for that now.

Yes, I loved cooking on the grill, and breakfast was one of my favorites. I would like to have a small commercial stove, but they are just too expensive, and there is nothing wrong with the stoves that I have.
I do have a cast iron griddle that fits on 2 burners that I use sometimes.
Best short order cook I ever met was at Brooks AFB, San Antonio TX. I was a student there in 1973, you came through his breakfast line once, placed your order when you were still about 20th in line and it was waiting for you by the time you got to his station. The next day, it was already waiting for you without having to say a thing. If you wanted something different you had better speak up as soon as you came in the door or it was just too bad, you ate what he cooked. How he kept all our orders straight, usually about 100 - 150, I have no idea. But he was a great cook.
Same thing at lunch where he worked the burger grill. Wish I could remember his name.
