We played this today at our games day and we all really enjoyed it. Even though I was pipped to the post to the Cobra MK IV to go with my Cmdr. Jameson.
Later on I drew the Pirate Hunt card which states (from memory) that I needed to go to a location, draw two cards and discard the most powerful. That done I attempted to bribe the remaining pirate with my 'Friend of Pirates' ability (sorry, again this is from memory so I'm paraphrasing).
The rest of the players objected and I ended up fighting him to an impasse and winning the point.
Should I have been able to bribe him with my ability? I understand that it was a pirate /hunt/ but in PL Jameson is a scoundrel, underscored by his Han Solo's grandad character portrait, surely he wouldn't be beyond coming to a mutually beneficial arrangement with his scoundrel pals?
Yep. You were correct and your friends were not.
Jameson is a scoundrel and his ability is especially for this kind of "purposes".
