On May 18, 2009, I asked the male employee to fill my vehicle with only 3 gallons of gasoline and he did not follow through on my request. He started the pump using my credit card, but did not care to stop the pump in time. I felt as though he was trying to take advantage of me as a customer, so that I would have to pay for additional gallons at a higher night- time price. I asked him if I could have a discount on the extra gallons and he refused my request.
