Carroll Fuel

I stopped by on Tuesday 12/23 for gas. I gave the attendant 4 five dollar bills and a 10. I told him I wanted 30 dollars worth of gas. He took the money and did not say anything except thank you. I pumped the gas and it stopped at 25.00. I questioned the attendant and he denied I gave him 30.00 dollars. I have tried for a week to contact the manager but every time I call, someone says he just left. I have heard this has happened to some other people. So I will not be using this station again. I have also learned that the thing to do is to ask for a receipt when giving these people money, before pumping gas.
