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?
