Please think of it this way. If you are wearing a Cross consistently in your life and you, say, go to apply for a job, go to the grocery store, panhandle, go to work, do you expect different treatment?
I see some comments here that the owner wears it to get business. First, is this factual? Second, (unfortunately) many have ousted God in America. The owner, by showing his faith, has taken a chance that most likely, lost business.
So please, this is America.
Be thankful that this business owner still has the RIGHT to wear a cross. This right is taken MUCH for granted.
