@Mickk I think I haven't made myself clear. I usually ask two or three times. To clarify things up - since I think too fast sometimes and use shortcuts - I usually destroy trader if second or third repetition of demand hasn't been met. Since what was outside bracket is a CRUCIAL thing in whole statement, if I see authorities after second repeat and trader sits around - things may go south. However, the fact that lawfuls usually do not tend to play with hostage situation and try to destroy pirate right away is pretty much resulting in destruction of a trader. And that basically is failure of lawfuls thinking about easy blue, not the safety of a trader as it should be done in roleplay.
I do not destroy traders after they failed to pay in less than minute after first demand. I'm sorry if you got the wrong impression.
On the other hand, it makes me disgusted that people do not even want to stop - and try to cruise away without any word. That's what makes me very sad and I fire right away after I ask player to cease its engines twice - and he fails to do so.
Insisting on running away is automatic fail to fulfill the demand no matter if it had been made or not. Or at least that's how I've been told by guys who are made in charge of the rules.
