The step that is not a part of uncovering a guest's hot button is C) Making assumptions about the guest's preferences based on your own experiences. The correct approach to understanding what drives a customer's decisions involves asking open-ended questions, using active listening skills, analyzing body language and non-verbal cues, gathering information from customers, doing root cause analysis, and conducting interviews with experts or people with direct experience.
