I like the story, and I like the way it is written. It kept me entertained for its 18-odd pages, and I felt grateful that it hadn't been me stuck in the car park overnight.
I was agonising over what rating to give it. It couldn't be a 1 or a 2, because those ratings would imply that I didn't like it. I don't think it is worthy of a 5, because that should be reserved for the very best books. So - it is a 3 or a 4. Then I hovered my mouse pointer over the rating stars and saw that Amazon makes it simple - 4 stars means 'like' and 3 stars means 'ok', so I'll give it a 4!
I picked up my copy when it was available free, but I see that it currently on sale for £1.53 in the UK. I think that is a lot to pay for a short story. I would be happier buying a collection of 10-15 such stories for £2-£3.
