The managers are all part of a kind of new religion, devoted to numbers, accounting, and corporate lawsuits. They all live an ascetic lifestyle, not going down to the aisles to obtain goods, but instead living off of the food that comes from the vending machines placed in the offices. Indeed, they pretty much live off of coffee and chips. They consider all other forms of food, and any kind of clothing aside from the suits passed down the generations, to be unclean and unusable. The only form of entertainment they allow themselves is composing strange poetry to be spoken over the PA system. The rest of the time, they study ancient account books, manuals, guides, and try to prove their number-crunching and history knowledge in an attempt to be summoned to the Holy Land and get to meet the Holy CEO.
The Holy Land, or rather, the Wal-Mart head office, is a massive mountain-like structure over a mile tall. It houses two things: the chosen of the manager class, and the robotic infrastructure that actually runs Wal-Mart. Both the AI Directors and the religious figurehead known as the Holy CEO dwell here. Anyone uninvited has to get past the most formidable security robots in the world. Many of the managers chosen to go to the head office are given obscure, meaningless roles in a fake beauracracy, which really only exists as a form of entertainment for the AI systems.
But for a normal walmartian, the head office is a fairy tale of a fairy tale, but the Manager's Office is an interesting dream. A manager is treated often like a wiseman who sits of a mountain, and is often listened to no matter how crazy he is.
