I always have to point and go "you see that thingy between the aisles??" because I don't know what else to call it.
But heads up to non-retail folk, we call the long free-standing coolers and freezers in ~~action alley~~ the middle of the floor bunkers.
We call that middle section with bunkers and ~~four-ways~~ smaller grocery displays "action alley". God knows why.
