Please don't use that whataboutism here. But, since you asked, businesses that offer services to the public can refuse service to anyone UNLESS they're refusing a member of a protected class, for being a member of a protected class. White restaurant owner kicking out a black lady because she's belligerent/drunk/whatever -- fine. White restaurant owner kicking out a black lady because she's black -- not fine. Religious bakery owner refusing service because it's Monday -- fine. Religious bakery owner refusing service because the customer is gay -- not fine. But again, please no more whataboutism.
