When the convenience stores first opened, they were called Tote'm stores because customers toted away the goods. In 1946 they changed the name to 7-Eleven to reflect the store's hours. Though the hours are no longer relevant, without that name change there wouldn't be free Slurpees today! As the company celebrates their 81st year, customers will be given free 7.11-ounce Slurpee drinks in special birthday cups. Last year the day was made a little more fun when 7-Elevens transformed into Kwik-E-Marts, and Slurpees into Squishees, to promote The Simpsons Movie. We suggest you follow Bart and Milhouse's suit and order the Super Squishee (made entirely of syrup) and "go crazy, Broadway style."
