"As a restaurant manager, it's your job to ensure your customers have an enjoyable dining experience and receive exceptional customer service from your staff. In an interview, expect to answer questions about your management style, conflict resolution skills, and ability to meet guests' needs. It is helpful to have dined at that restaurant ahead of time so that you are familiar with its menu items and customer experience."
if someone complain about bad service, how would you handle the situation?
Apologize. listen to the guest. correct the situation, follow up with the guest to see that you have met and/or exceeded thier expectations.
