You Thanked the Clerk Like You Were Their Boss

Why this phrase

Hotel front desk. Kōfuku plays the guest who says ご苦労様です to thank the clerk, because a textbook listed it as a polite thank-you. Hana plays the clerk, warm, not angry. That line goes downhill. A boss says it to staff. From a guest it sounds like you rank above them. お疲れ様です is the peer greeting and already a video. To staff, just say thanks.
