But, it is basic freedom of association for business owners to be able to pick and choose customers.

In the case at hand the business owner was free to choose his employees, and he chose not to retain one who refused service to a customer. It's win-win-win. The business owner gets to keep his customer, the now-former employee gets to exhibit his cheap moral posturing, and the customer gets to enjoy the meal best served cold.
