Her Side of the Road
In my pedestrian opinion, published literary work has very little diversity of point of view. You should think of working at a gas station as an opportunity to give your readers a setting and daily problems that they simply won't get in another setting. I once saw a young guy working at a gas station. He was alone and he was running his legs off pumping gas and answering the phone etc. I was in a physical position to spot right across the street a girl using a pay phone to push that kid's button. She'd let it ring until he got to it, then hung up. She was obviously in love with him. She just somehow didn't dare tell him. Gas stations. Your thumb is somehow on some sort of societal pulse.
