Could you tell me if the word for adds anything to the meaning in the following context. It's from the sixth episode of the tenth season of Friends.
Chandler: Look, I'm sorry I didn't give them your tape. And I promise, next time to submit you whether I think you are right for the part or not.
Joey: That's not the point Chandler. The point is that you lied.
Chandler: I know. You're right. What's it gonna take for you to forgive me.
How the meaning would change if Chandler dropped the for?
