Also, Target stores here usually seem to be cleaner and neater, whereas Walmart stores frequently seem to be dirtier and the shelves look at bit ransacked and picked-over.
However, this does vary a lot by location. When I lived in northern New Jersey, the Walmarts there were a horror show: nasty floors, shelves looking like people just went through shopping in preparation for a hurricane, etc., whereas the Targets were nice. The customers at the Walmarts also seemed to be all poorer minorities, black and hispanic (I'm white), whereas Target was full of white and middle-class-looking black people. However in some more rural locations in the South, the Walmarts I've seen were clean and neat (but there were no Targets around).
I feel really bad for the people who lost their jobs.. for young people in their first job, it might be okay. For older folks who probably quit a job some place else, it is really a hard experience.
Walmart stores in Toronto that I visited, definitely seemed crowded with long check outs. Other cities in Ontario, the checkouts seem to be adequately staffed. I'm surprised how different Walmart Canada is from the US operation!
The one I go to when visiting Arkansas is better in almost every way, possibly owing to attention of the "home" regional management.
