Call centers and contact centers seem to take great delight in moving their people around before they have a chance to get comfortable in one place thus moving their agents to a new desk location on an ad hoc basis. Office amnesia is simply a temporary state of forgetfullness where you can't remember where you are sitting and end up turning back to go a different route. Its duration commonly lasts only a couple of seconds but very irritating. This usually follows a visit to the bathroom, vending machine, printer or photocopier.

Me: That's Office Amnesia - its only temporary... until you move desks again.
