Murder Kroger has an obvious background, and it’s own wiki. They bulldozed the old murder Kroger, and a fancy new one sits almost on the same spot:
Disco Kroger was right next to the Limelight, a mega disco from the 1980’s that was widely known. If you shopped in that Kroger in the Limelight’s heyday you’d frequently see customers that staggered over from the disco.
