Marcus, a prolific shoe buyer, refuses to be assisted by male store clerks. the owner of your shoe town, therefore, informs his staff that only female employees should attend to marcus because he does not want to anger a patron of his store. one of the male clerks, austen, believes that this is illegal gender discrimination. also, since part of his incentive pay is based on meeting the monthly sales target, he feels that this policy illegally denies him the opportunity to earn incentives because of his gender. is austen correct?
