"Can you come up with one that....Oh...I don't know...pertains to the discussion we're having?"

Multiple have already been named in this thread. Including by you. Your example of the skinhead in a. jewish bakery. I explained to you why they could be refused service, you disagreed because you don't understand the law. Hitler cake. KKK with a burning cross cake. All could be refused. But no matter how many "name one" examples are given here you've demonstrated that you will ignorantly disagree with them all.

A business can refuse service for just about any reason you can imagine, EXCEPT if that reason is based on a class of person that is protected in anti-discrimination law, AND if that reason is applied to all customers EQUALLY. Pretty simple concept, not sure why you are unable to understand it.
