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.
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.
