jamb,
I think "Petrol Station" is great!
I read the review which was a 1-star and the reviewer's comments- although I think 1 star is way too low, I can see the point made. In the beginning of your story, Valerie's thoughts vacillated between fear and retaliation; however, I saw this as more realistic and that is one thing I enjoyed about the story. I think you did a good job getting into her mind and explaining it to the reader.
I understand you would find the one star rating annoying, as it brings down your average unfairly. But more good reviews- which are well-deserved, will take care of it.
I just submitted a story for the first time and I am curious as to how I will react to the reviews. I imagine it's difficult to have that necessary tough skin, no matter how prepared I think I am.
Anyway, good job on the story and don't worry about one bad review that seems unfounded.
