Amren knew absolutely nothing about mechanics, but she caught on quick on what the Human male was trying to do. And it was clear that the smuggler was trying to rip him off.

She crossed her arms and gave the smuggler a doubtful look. "That piece of junk? I wouldn't pay half a munny for that."

She turned back to the Obi-Wan and pointed back over her shoulder. "I saw a vendor about twenty stalls down selling actual brand new ones for less then ten munny." That was a lie, but the smuggler didn't know that. Hopefully the Human male will realize though.
