Staff centers, what good are they? The only thing I have been able to discover that they do is allow the already lazy zookeepers to stray away from their assigned exhibits, and the maintence guys to "get supplies". I was hoping the zookeeper's AI might rise and they could take care of exhibits more efficiently as they do when trained in ZT. But I haven't seen any of that. The only thing I notice that the staff center does is drain money every month. Has anyone found a use for them?
