Do you think any business should be able to serve or refuse to serve anyone they choose?
I sort of think so but where will it end? Obviously if you choose not to serve a certain race or religion it's illegal but if its your shop/bar/LFS surely it's your choice who you let into the place.
As a customer I would choose not to go to that bar if I had a face tat or trump hat even though they have now changed the rules, I'm sure there's plenty of other places that would be happy to take my cash. It's weird, like the *** guys fighting the baker over the wedding cake, why did they make a fuss and not just go to another baker. I can understand they were annoyed but money talks and not many small independent businesses can afford to lose business, if they want to add to their troubles by restricting customers then they should be free to do so and anyone offended by their practices can stand out the front and laugh when they put up the "going out of business" sign.
