The following is an actual NPC Conversation triggered wandering around Anchorhead on Tatooine.

Customer: Hey! This droid you sold me is a piece of junk! I want my money back!

Jawa: No refunds! You keep!

Customer: But it’s busted! Stupid thing’s vocabulator broke down as soon as I got home. Won’t say a word now!

Jawa: Vocabulator not broken! Is feature!

Customer: A feature? Don’t give me that! What good’s a protocol droid if it can’t even talk?
