If you think about it, the reason behind this move might be to separate the two groups. Anglos go to Walmart, Hispanics go to the Spanish equivalent. Problem solved from their end.
Maybe with the two new stores for them, it might work that way. Here we had one WalMart, and the "minorities" (who just about out number whites now) raised a ruckus wanting one in another part of town where most of them live. So, they got a brand new shiny store. They all still come over to this one and we tend to go to the new one (if you go) where there are fewer hispanic shoppers and a cleaner store.
