Perhaps.
But refusing service to someone simply because of what you assume by their ethnicity or skin color - and the assumption that they 'hate' you on account of those - is stupid.
Maybe.
And maybe not.
I know a certain amount of people hate me. Some for the shade of my skin, some for my religion, some for reasons that only exist in their rather vivid imaginations. The world is not a benevolent place and becoming even less so.
In my job, which is at least partly a service job, I do not refuse service to anyone but I also do not assume benevolence by people I do not know either.
Too many people have suffered and died because they turned off their people warning system.
Mine is on high at all times.
I have some innocent and harmless people to protect.
And that is not my job but my career.
Do you know any individuals who hate you for the shade of your skin, your religion, etc? and have they done anything to harm you?
