I just called Pepsi's toll-free number printed on my bottle of Mountain Dew to tell them I was disappointed that the soda was flat. No, Steph, keeping it in my office refrigerator for three weeks shouldn't mean "of course it's flat." :-P It's got a November 1st, 2004 freshness date on it, it was kept cold... it should still be good for months! The nice lady is sending me coupons, to which I really wished I could say, "But I'm thirsty NOW!" and tell her I waned an immediate replacement of my defective soda.
