Sure, if they suck at RP. Duels in general go unanswered and you know why? Because a lot of people assume that only good sword fighters offer duels. Smarter players make use of that to their advantage by offering duels, knowing their is a 80% chance that the action will frighten off the other player.
That's a hell of a risky strategy. I can see it working fine right up until you mess with the wrong character. Best to limit the number of times you gamble on this.
