Discrimination doesn't stop being discrimination even if it causes lower costs and/or might be rational from the perspective of the business. It may be possible, for instance, due to a combination of structural and cycle of poverty factors that a black person in the part of town your store is would be more likely to commit a crime - that doesn't mean the store is non-discriminatory if they choose to ban all black people. The point is that you can't make decisions about people based on a protected trait, like race or disability. (To be clear, the black crime example was used because I think that we can all see the most blatant forms of discrimination in race-based discrimination and the "black crime" trope is one of the drivers of that discrimination)
