Do you have any specific examples? When you work in a restaurant, it is important to have positive customer feedback. This ensures that people keep coming back, and it is also a great way to get referrals. In the event of a customer complaint, it is important to take quick action so the problem does not escalate. Sometimes the interviewer may provide a hypothetical situation for you to resolve. Make sure to discuss what you would do to rectify the problem and provide examples from the past.
