I must not be too observant but I've only recently noticed in several stores how our friends from south of the border help themselves to all kinds of things from food to diapers to milk. I walked down the candy aisle in Wal-Mart just before Valentines and they had some Easter candy out as well. A whole Mexican family, adult and children, were munching on those individually wrapped cream filled easter eggs. At Sam's an employee was complaining about an open container of milk. He told me they just help themselves to it--pour what they need into the baby bottle and they are on there way--same thing with diapers.
