I am not sure how locate() works, but wouldnt it be likely that this would shoot the slip at some random somebody whos waiting at the window and no cargo staffer is there as well? Also, it would be shooting at borgs, corgis, monkeys, slimes too if present.

I cant think of a real good way to only spit this paper at cargo folk, but it would be silly to shoot it at people/things that cant really do anything about it.
