Cant wait for Jimbei to fight Luffy for beating Arlong, and pretty much sure sengoku hat is the pirate summit
That is a misunderstanding thanks to the mistranslation.
The original said by Jinbei :"I both want to thank and apologize to you (Luffy), but it's not the time, we have to focus on our target". Jinbei want to apologize Luffy for what Arlong did.
