You want your rights, how about their rights? Just because a business is "open to the public", doesn't mean it should lose it's right to self determination. It should be able to choose its customers with the freedom you have to choose a business to work for you. A business can turn down a customer for many reasons, one of them should be simply...I don't like you.

Why should you have the "right" to choose, but they don't? Afraid you'd be left out in the cold? If nobody wants to do business with you, it's probably you that needs changing.
