Free Slurpee Day! Wait, Maybe Not

Today is 7-11! Typically a day we get excited about in the 4-3-2 because it means free Slurpees for everyone! But wait...we no longer have 7-11's? Do we? They've all become something else. 

Think about it, it seems like from 1 day to the next all the 7-11's had disappeared and before we knew it, something called DK was popping up in their place. Now they DO still have the 'Slurpee' machines but what do we call them now? Is free Slurpee day as we once knew it now a thing of the past? Has anyone seen a 7-11 in the Permian Basin lately?
