I imagine it is the size of the corporation. So many different people in so many different places and one store is different from the other. It is difficult if not almost impossible to know what to expect when you go into a new store when you work for Walmart. Although all of the stores I have worked in have seemed the same, there are many things in each that are different. I have worked for store managers that seem real. I have worked for store managers that are biased and distant. I have worked for liars and for very honest and ethical store managers.
