Convenience store chain 7-Eleven has 81,000 locations globally, meaning they serve lots of coffee, and they even claim to have invented the concept of to-go bean juice in 1964.

The brand hasn’t slept on its to-go innovation, adapting to changes in how consumers drink coffee. 7-Eleven kept up with the times by adding new flavors, toppings, syrups, iced coffee, and seasonal offerings, staving off competition from other convenience stores like Circle K and specialty coffee chains such as Starbucks.
