Look I get needing money and not wanting to pay. I always personally pay pirates if they can catch me, but they do have to earn it as I am fairly good at getting away.
But hell, if your cargo isn't worth the cost - at least find a way to RP having him just kill you. Make up some story about how "THIS IS THE LAST DAMN TIME I GET ROBBED, MY CHILDREN ARE STARVING!!" and go postal or something. Anything can be RP'd.
