Top Gas and Mini Market

I have been going to this gas station for over years because their gas prices usually are lower than other gas stations in the areaOftentimes when I paid with my debit card and the amount requested is more than the required amount to fill up my gas tank, I would be given the difference in cash after about a month of this, I was requested to return on another day to receive the amount in back in gas I have even been requested to pump my gas for the amount I wanted and then pay for it Recently I went to this gas station for gas as usualI requested $in gas and the charge was made to my debit card I only used $of the requested $ The real problem is that none of the employees know how to resolve the issue correctly in the first place by putting into the cashiering machine the difference between the amount of gas received and the actual amount of the sale after the card has already been charged for a higher amount I was asked to give the merchant my debit card whil
