The 7-Eleven convenience store chain started out as the "Southland Ice Company" on the corner of Twelfth and Edgefield in Oak Cliff in 1927. It has now evolved into the world's largest convenience store chain with stores in 16 countries.
"Every time you come in we want you to feel like there is something new and better for you," said Laura Gordon, 7-11, Vice-President of Brand Innovation.
The chain is now celebrating 85 years of serving customers.
Originally their name reflected the hours they were opened, 7 a.m. to 11 p.m., seven days a week. Now its stores are open 24-hours a day, 7 days a week, a first in the nation.
Another first was the Slurpee, a soft frozen flavored drink.
On Wednesday, July 11, to celebrate the chain's anniversary, 7-Eleven will give away free Slurpees from 11 a.m. to 7 p.m., in 7.11-ounce cups.
"Whether you're cherry and coke, or coke and cherry it all has to do with what you make at the machine that makes your Slurpee your own," said Gordon.
7-Eleven employees like Rachel Jones are getting ready for the crowds.
"We get to see different customers that we don't usually have," Jones said.
