How many remember Carroll's 15-cent hamburgers?

At one time there were over 150 franchise outlets around the country.  New York State had the most of any other state with many Carroll's restaurants found in Upstate.  In the 1970s they folded into Burger King and today there are over 700 Burger King restaurants in the U.S.

Do you remember their saying?:  "A Serving a Second."  Do you remember their signature sandwich?  "The Club Burger."
