Let us consider the evidence.
At first glance, this appears to your average sign announcing to the world that fine groceries, produce and sundries may be purchased within, but upon closer inspection we find...
Spiky bits! The whole sign is covered with spikes, presumably a mutation provided by the dark gods when Kroger gave their devotion, indeed their souls, to Chaos!
The far entrance, like the main sign, looks innocent enough. "Clearly if it is food you seek, here you will find satisfaction," it beckons.
But no! More spikes! The only food you will find is the taste of your tears as you fall before the unstoppable hordes of the Ruinous Powers!
A closer inspection below the "food" sign reveals the image of some dark goddess or daemon! Could this be the work of Slaanesh?! Or is the entire pantheon of Chaos in league to corrupt this establishment?
Shameless! They are even advertising that they will intentionally inject flu viruses into your very blood! There can be no mistaking the noxious touch of Nurgle upon this wretched place!
The final piece of evidence. The siren song of Chaos, set before man to appeal brazenly to his basest of instincts. "Buy one," the seductive voice croons, "and get one free." Who can resist this foul temptation?
On the down side, I will have to start looking for another grocery store at which to shop. The =I=nquisition will undoubtedly have purged this one by the time I need groceries again. I suppose I should be happy that it's not just planet-wide Exterminatus. I must remember to look on the bright side.
