The CEO wrote an article that I read that he would promise that Walmart would do a better job of keeping shelves stocked and more cashiers to checkout customers-He needs to re read his own article-Walmart has the worse stocked shelves I have ever seem and still have to wait in long lines to get checked out- so much for customer service .
