Shell Service Stn Dlrs

This is the worst gas station ever. I came in today and made a purchase, I gave the female attendant $ 10 my change should have been $ 4. She refused to give me my change. She said I didn’t need to make my purchase and she didn’t have to take my money but openly refused to give me change. She said she had no singles however when she opened the register to take my money she clearly had change in her drawer. I have never been to an establishment that just blatantly refused to give a customer change for their purchase. I can understand if my change was a few cents but it was $ 4. I will never use this gas station again and I will be contacting the manager. I wanted to give this review zero stars but Unilocal won’t let me post unless I give at least one a star.
