An idea for Bib’s dialogue.
3PO: We bring a message for your master, Jabba the Hutt.
Bib: De Jabba wanga?
R2 beeps. Cut to wide shot of droids, cut 3PO mentioning gift. Keep R2 beeping, cut to a close up shot of R2 beeping. Even add a reaction shot of a Gamorrean if you wanted it to last longer, but the idea is R2 is telling Bib the message, so R2 needs to beep a little longer than usual.
Bib: Ne Jabba no bodda. Jabba won’t bargain.
Bib: Eez ai ota. He has what he wants
Bib: Kiz ata u mudi. But we do need droids…
Bib: Me chadda so gudi. So we’ll accept this gift!
C-3PO: Gift? What gift?
Bib: Lu cha! Take them!
