Step-by-step explanation:
Johnson is committing rebating by offering potential clients courtside tickets to a professional basketball game in exchange for purchasing an insurance policy. Rebating is an unethical sales practice where a seller provides a buyer with an unauthorized benefit to induce a purchase. This is considered unethical as it can be seen as a form of bribery and may violate fair trade practices by offering an incentive outside of the insurance policy's benefits. It's important for sales practices to adhere to ethical guidelines to maintain consumer trust and a fair marketplace.
