Ismeralda Marcus, a Prolific Shoe Buyer, Refuses to Be Waited

Ismeralda Marcus, a prolific shoe buyer, refuses to be waited upon by male shoe store clerks. The owner of Your Shoe Town therefore informs all of his male clerks that they may not wait on Ms. Marcus, because he does not want to anger his best customer. One of the male clerks believes that this is illegal gender discrimination, and that since part of his compensation is based on his sales volume, he feels that this policy illegally denies him the opportunity to earn compensation because of his gender. Is he correct?

A) Yes, because gender-based customer preferences are never legitimate.
B) No, because gender-based customer preferences are legitimate business concerns.
C) Yes, because gender-based customer preferences are not legitimate unless they implicate a legitimate privacy interest.
D) No, because the shoe business does not affect interstate commerce.
