Is the following review positive or negative?

Being from Chicago I always preferred Jewel to Dominicks. Same is true out here with Albertsons on top of Safeway. Went to fill up my gas for price listed on sign. After sliding my card with clerk, went to pump my gas. I noticed the pump price was 10 cents higher than their advertised price....went to question clerk, and he says the advertised price is for cash/debit purchases. I asked him why he wouldn't mention that to me before I swiped my credit card. His response was it's not my job!! Shady, shady....beware....
