The reddit AMA author seems to have worked at a ‘traditional’ FC where there are miles of bookshelf or pallet style storage. In this layout it is difficult to place optimized restrooms as one pick worker may cover half of a million sqft building in a shift. Newer, robotized FCs have much more tightly packed, human-inaccessible storage zones and have restrooms a reasonable distance from static pick workstations.
