So, to be clear, they told you: "We followed you because you were black." That's what they said? I find that hard to believe - and find it to be incredibly stupid if they did. But, even if they did admit to that, you may have little more at this point than a complaint to make to management. You'd have a long way to go to make a successful civil rights lawsuit, and it might cost you a pretty penny just to get into that game unless you managed to snag some crusading civil rights attorney who already has extensive knowledge of the business's actions (and, maybe, some actual damages to someone).
