This was very well crafted. I've few complaints about your descriptions or presentation. Muse, as she is well known for, nailed most of the technical gaffes, so I won't redundantly mention them. Only two things struck me as wrong or odd and should have been changed.
First, no taxi ever arrives on time. What ever were you thinking? The other was "tinfoil". They don't make tinfoil for such uses these days. Instead they use aluminium foil. Heh. Yeah, I am really digging deep for something to bitch about. Unlike Muse, I would have suggested using "red metalic wrapping paper".
Feel proud of this little tale. I had to dig so deeply to find a problem that my "complaints" are mostly in jest. I especially liked the ending. It was frightening and funny all at once.
Show me more.
