So this is what happens when I forget to take my trusty notebook with me and find myself with some downtime. I start scribbling bits of story on whatever scraps of paper are at hand. In this case, a receipt from a chain of DIY stores that I found floating around in my handbag.
Bits of story scribbled on the back of a receipt
The scene in question is from a novella currently entitled Green Skin, Red Blood. The title may well change down the line, because the focus of the story has changed quite drastically to the point that it no longer fits.

Don’t know if it helps, but Spock had green blood because his was copper-based rather than iron.
The protagonist of the story basically keeps getting mistaken for a member of a race of evil aliens called the green-blooded Molongans throughout. She tries to prove that she’s not a green-blooded Molongan and that her blood is in fact red. There’s a lot more to it than that.
