From Stained Apron:
"Order FOR little Johnny, no matter how cute you think it is to see the waitress trying to coax his order out of him. You KNOW what your kids eat. Avoid the trying process of the child changing his mind 20 times or refusing to order while the waitress stands there waiting and waiting and waiting."
That made me laugh. My mom always followed that rule. I took her out for her birthday a couple of months ago (i'm in my 30's now) and she ordered for me. Old habits are hard to break I guess
