It is the same here in Montreal . The place is a zoo !( I never go to walmart for many reasons that would start a debate and I dont want to)
But basicaly , stores are like that because people go anyway, as we have seen in some of the answers here. In some places , the custumer as no choice because everything else has closed because of the arrival of walmart. And to keep the prices low , they need to cut somewhere: service and " cleaness". Walmart has a very precise amount of profit they have to generata , and they will do what ever thay have to not to deviate from this amount of profit.
