I went to the valero gas station in Farmington Mi on 10 mile rd . i cashed in my lotto tickets and was asked if i wanted cash back i said yes but put it on pump#2. I proceeded to pump the gas but noticed i was being charged the price for credit card. I went back inside and informed the clerk. He told me he didn't know but he pushed cash. I go outside to take a pict. To show the clerk and he insisted that he pushed cash. He then tells me after i left and returned to show that my receipt says prepay cr. He informs me that when you cash in lotto tickets they charge a percentage when you get gas. That doesn't make sense at all.
