Final answer:
Julie should professionally and kindly address Joe's soreness complaints, offering assistance and feedback, and ensuring he feels heard to maintain a good reputation for the practice.
Step-by-step explanation:
Julie should approach the situation professionally by kindly addressing the client's concerns and offering assistance. Her best action is to listen attentively to Joe's complaints about his soreness after the massage treatment and to provide thoughtful and considerate feedback. She can apologize for any discomfort he experienced and suggest ways to alleviate his soreness, such as drinking plenty of water or taking a warm bath. If necessary, Julie might also offer to adjust future massage sessions to better suit Joe's comfort level or connect him with Maria to discuss his experiences directly. It is important for Julie to ensure that Joe feels heard and that his feedback is taken seriously, which can help maintain a positive reputation for the massage practice and possibly retain him as a client.
