There may be those who believe that repeated purchases over a very long period should be a sufficient product endorsement. Forgive my brazen demure, but excellence of the level of Coke Zero should be heartily presented. Believe a gentleman of advanced age with limited genuine pleasures: Coke Zero is an assured delight whenever and wherever it is enjoyed. For many of us, that is regularly throughout the day. It is much appreciated, and every sip is savored.
