We bought milk today at slip time h19:28 just to find out its sour, then returned it at 19:55 just to be confronted by an argumented assistant manager with no manners. He mentioned that they don't sell sour milk and that he rather just refund us so we can go buy milk else where, he obviously do not no what petrol cost do drive up and down. then my son mentioned we need the milk and if we can get another milk please. Just then came to my frustration that the milk they returned was sour aswell. We need milk for a baby. PLEASE HELP!
