Eyewitness reports on Sunday, near the end of the hottest July ever in Los Angeles, indicate that the Starbucks store at 2919 Los Feliz Blvd. in Atwater Village ran out of iced Venti cups.
To compensate, Starbucks offered two iced tall iced beverages (12 oz. each) for the price of a one iced Venti beverage (24 oz.) - a savings of 50 cents to $1, depending on the order.
The report has not been disputed by the Starbucks corporate "rumor response" department. Although, at press time, it was not clear why an iced Venti beverage couldn't be served in a hot Venti cup.
Maybe there's a rule.
