Sorry but duelling is pretty close to murder.
You back down, you'll be laughed at, ie, lose your "honour"; you take it all the way, and you'll either lose your life, or take someone else's.
Wasn't it duelling that took the second US president's life?
I think you're all underestimating modern society's total absence of backbone. It is considered an insufferable outrage if too many pickles end up on your giant-mega-burger. If the person who messed up the order could just declare a duel, how often would the whiner accept just to save face. I'm pretty sure reason would prevail most of the time, and people wouldn't risk their lives about the honor our culture gave up over a hundred years ago. As long as it is made acceptable to back out, it would at least stop people causing a bunch of trouble for reason they don't even care about, just because they think they can sue.
Whiner: "Waiter, you gave me the wrong drink, this is unacceptable, I demand a full refund-"
Waiter: "AT DAWN WE DUEL!"
Whiner: "Here's your tip..."
