Be careful when bargaining for release from captivity that you include everyone you intend to. All the people could easily be interpreted as not including elves or dwarves or aliens or whatever.
On the other side, this makes a great loophole for setting up agreements with potentially untrustworthy or hostile negotiators. Or just ones you want to rip off.
Teebo: Right, you're for it now.
R2-D2: What? You just agreed to release us all.
Teebo: The "humanoid resources". Which you ain't.
R2-D2: Why you...
R2-D2: I'm better than humanoid.
C-3PO: Now, now, Artoo, all solvent beings are equal in the great economy.
Teebo: But 'e's got no appendages!
R2-D2: Here's an appendage for you!
C-3PO: Dloids are commercial entities too.
R2-D2: Treat me as humanoid, and in return... I won't zap you any more.
