The store near me had a lobby about 10x100ft. There was a simple glass door separating it from the shoppping area which was just counters around the perimiter and pegboards on the wall.
The shopping area at this location sometimes had more than one employee working, sometimes they would handle two patients at a time. Perhaps 3 people at most back at a time.
They just removed the wall and pushed the counters and pegboards up into the lobby. From outside the building you look inside and every wall and shelf is filled with product.
I really do think it was just above moving more product.
