A worker does his best to show off his goods to passers by, they do their best not to acknowledge his existence. They would probably walk straight through him if they thought it possible. Italy has an abundance of foreign workers, some are forced workers working for local crime syndicates, some are just trying to do what they can with what little they have. It is hard, if not impossible, for the passer by to make a distinction between the two.
We should however, remember that every person has a story and every person deserves to be given the same amount of respect as the next.
