Dock at a Domina station and donate a single Star Wars DVD. See what you get. I got the following:
0018a002/1613826: Error evaluating <OnPanelnit>: No binding for symbol ["We thank you for your good intentions; may Domina be with you. Always."] ###(eval (@entry 3)) ###
Also there are many food and luxury items that get the "These *item* are useful to us in serving Domina" reply, but when you donate them you get the "We thank you for your donation and your good intentions. Go in peace." Well. You're welcome, you old tightwad bats. Maybe you should loosen your headbands a bit.
