My daughter and her friend stopped in at the mac's gas and variety in Ruthven to get gas for her car. After she finished fueling up she went in to pay and immediately was told to get to the back of the line (because it was busy) by Karen who was cashing people out.. While standing in line the lady in front of my daughter let her go ahead of her. Karen called my daughter up to pay and then proceeded to tell her in a very rude way that she could pay at the pump. After my daughter told her she was just paying 40 dollars for gas and that she preferred to pay inside. Karen replied rudely next time pay at the pump, even though that half the debit machines at the pumps do not work..
