"Honor Killing" by Ray Tabler, on Escape Pod episode 321.
This is a sly, but fun, little story about a cargo hauling space captain who has an encounter with some cute little aliens in an effort to get some money so he can get away. The cute little aliens need a killing done, and since Humans are notorious killers the captain won't mind doing this deed for them.
The captain sees the aliens as cute and quirky, but the aliens have their own racism, or specism (speciesism?), so the story basically revolves around a culture conflict with constant surprises for the captain. This story is fun enough if you're in the mood for cuteness.
